Update lxpanel 0.9.3:

0.9.3
-------------------------------------------------------------------------
* Finally fixed battery calculations, it missed Power so left time was
    always at zero.
* Fixed task window raising on drop file on it (was broken since 0.9.0).

0.9.2
-------------------------------------------------------------------------
* Fixed battery selection if battery detached but another is available.
* Fixed battery percentage calculations if charge isn't available but
    energy is, it appears broken in 0.9.0.
* Fixed wrong state change on task button when hovered, it shouldn't
    receive selected state until window has urgency.
* Fixed wrong flat button appearance when hovered, it wasn't flat.

0.9.1
-------------------------------------------------------------------------
* Fixed build failure without ALSA.
* Added alternative mixers if build using OSS.
* Fixed panel flicker with some window managers.

0.9.0
-------------------------------------------------------------------------
* Added support for laptops with multiple batteries.
* Added a way to scroll through workspaces by using the scroll wheel over
    the deskno plugin.
* Bunch of fixes for GTK+ 3.0 compatibility.
* Fixed outdated lxpanel man page.
* Fixed weather locations query (since YQL was changed recently).
* Converted space plugin into internal PanelSpace widget in liblxpanel.
* Converted task button into widget class to avoid ambiguous code.
* Added support for third-party plugins localized descriptions.
* Implemented "lxpanelctl command ..." to send message to panel plugin.
* Added APIs for PanelIconGrid to draw focus on drop.
* Converted launch button into widget class for more easy management.
* Adjusted PanelIconGrid: min spacing is now 1, no_window flag is now
    left unset by default, spacing is taken into account on overall size
    to be consistent on chosen orientation.
* Implemented dropping file or folder onto launch bar to create launcher.
* Implemented dragging launchers around launchbars (between panels too).
* Implemented dropping file or folder onto free panel space to create
    launcher.
* Implemented dragging launchers from launchbar to some free panel space.
    When launcher dropped onto another place and former place's launchbar
    becomes empty, it will not be replaced with a bootstrapping icon (as
    it happens when last launcher is removed via configuration dialog)
    but launchbar will be removed from the panel instead, that behavior
    is more obvious and sensible.
* Added stripping scheme from URI menu://applications/... when a launcher
    is created, only menu-id itself should be used.
* Implemented moving plugins across panel by means of middle button drag
    and drop, i.e. middle-click it then drag, and plugin will follow the
    mouse until middle button is released.
* Merged 'volume' and 'volumealsa' plugins into single plugin which uses
    the same interface but different driver, in dependency on how it was
    built - either OSS or ALSA interface is used. Name 'volume' is used
    for simplicity while 'volumealsa' is supported for compatibility.
* Made default channel in 'volume' plugin definable in config. If there
    is no config statement then plugin finds first usable one, the same
    as before.
* Made clicks for Toggle Mute, Show Slider and Open Mixer actions of the
    'volume' plugin configurable. Defaults are the same: left-click shows
    slider, middle-click toggles mute state.
* Added support for 'PCM' and 'Headphone' channels for OSS mixer.
* Added support for other (not default one) ALSA cards in 'volume' plugin
    via 'CardNumber' setting.
* Added hotkey support into 'volume' plugin to be able to use multimedia
    keys for volume changing directly by plugin.
* Fixed missing libkeybinder initialization (keybinding did not work).
* Fixed check for attempt to add a binding for the same hotkey which is
    already bound elsewhere.
* Added a configuration dialog to the 'volume' plugin with all the new
    settings available to choose and set, including preset of discovered
    mixers, with ability to type own command as well.
* Fixed crash on action on task window which was deleted while task menu
    is still opened.
* Fixed "dynamic" panel width allocation.
* Fixed PanelIconGrid allocation in rigth-to-left languages, it was wrong
    so some icons might be invisible or placed under other plugins.
* Removed call to gtk_widget_set_style() from volume slider to fix colors
    of current theme.
* Changed icon size handling on task bar - it may now maintain the same
    size as rest of icons. It may affect users who are used to have them
    smaller, it's why this feature was made configurable, corresponding
    config variable is UseSmallerIcons and default is 1 (old behavior).
* Changed volume slider popup behavior - it now hides when loses focus.
* Fixed invalid memory access in weather plugin.
* Fixed incorrect reporting units on "Feel" value in weather plugin. YQL
    always reports Fahrenheit degrees there.
* Added a safeguard on menu cache returning items with empty Exec line.
* Fixed maximizing windows using task bar, GDK functions not always work.
* Fixed wrong bind of preferences dialog to the panel, which resulted in
    other dialogs appear on the same workspace where preferences was.
* Expanded launch buttons active area to launchbar borders so if clicked
    even into desktop corner, it should activate button at that corner.
* Fixed few memory leaks in 'batt' plugin.
* Removed unwanted conversions with energy for charge in 'batt' plugin
    which will mess up tooltip indications, and may make rate/percentage
    calculations invalid.
* Replaced Xclimsg() with Xclimsgx() to be screen aware with X11 message.
* Added a workaround for WM like MWM which does not properly resize down
    widgets of panel kind. It still leaves artefacts but is better now.
* Added a workaround on GtkBox behavior which does not send allocation
    requests to children in some cases, so resizing of launchtaskbar on
    panel height change was broken.
* Fixed PanelIconGrid layout on vertical panels with more than 1 column.
