sfeed_curses: Update to 0.9.10

Changes:
0.9.10
------
 * Fix a possible memory leak when used with ncurses and when resizing the
   window. The terminal was reinitalized using setupterm() which would leak memory
   and it is also very inefficient to do so, because it rereads the terminfo
   entries.
 * Fix a possible memory leak when used with ncurses and when exiting from an
   interactive program and restoring the terminal for sfeed_curses.
 * Fix an issue when the sidebar would be > 256 columns long the text on the row
   would not be displayed. Especially noticable in the monocle and horizontal
   layout in fullscreen on bigger screens.
 * Fix a silent truncation which would make searching on titles with > 1024
   bytes not work on these truncated bytes.
 * Fix right-click plumb not respecting the environment variable
   $SFEED_PLUMB_INTERACTIVE flag (but the keybinds did).
 * Fix drawing/updating of the initial items scrollbar when switching to the
   monocle layout.
 * Fix to restore the terminal state more gracefully when it could not be
   correctly initialized (for example with an invalid $TERM set).
 * Fix for correctly decoding mouse buttons 6 and 7 (tilt scroll) using xterm
   X10 decoding. These buttons were not used, but still :)
 * Fix: when the pane items or scrollbar are outside the window to not draw them.
 * Do not clearscreen() when the window is dirty.
   This makes sure there is less flickering in xterm and urxvt, like on a window
   resize or when adjusting the sidebar.
 * Add the keybinds J (shift-j) and K (shift-k) to go one item up or down and
   also open it for faster navigating and checking new items.
   Feedback idea from Hadrien Lacour, thanks!
 * Also allow scrolling when the position is exactly on the pane its scrollbar
   and fix mouse button actions that don't depend on a position in a pane.
 * Implement extended SGR mouse-decoding and also improve X10 mouse decoding:
     * When the terminal emulator supports SGR mouse-encoding then it can
       encode x, y values beyond 224 columns and rows. This is useful for big \ 
screens.
     * Map the side-buttons (back, forward) to switch panes. Useful in the monocle
       layout.
     * Implement keymasks (shift, meta/alt, ctrl) and pass them to the function
       mousereport().
 * Improve resizing the sidebar:
   * Avoid unnecessary redraws in some (rare) cases.
   * Clamp the minimal and maximum value when adjusting the sidebar size
     depending on the layout.  This also fixes an issue in horizontal layout mode
     when the sidebar is 1 column high. It would require 2 keypresses (instead of 1)
     to increase the sidebar. This was an injustice to the fingers.
 * After toggling showing new feeds or when reloading feeds try to select the
   same feed again.
 * Code-style improvements, typofixes and minor documentation improvements.
