Update "xchat", "xchat-perl" and "xchat-python" \ 
package to version 2.8.2.
Changes since version 2.8.0:
- Updated translations (be, ca, cs, el, hu, sv, uk, zh_CN).
- Fixed the "Save As" function saving to the wrong folder in the
  URL Grabber.
- Fixed a bug in the "Copy Selected Link" URL right-click on
  non-ASCII chars.
- Fixed small bug: #100239 buffer overflow in setup dialog.
- Overhauled the Alerts section of the settings and added support for
  opening system-tray balloons (libnotify required).
- Implemented /TRAY -b command on unix.
- Nick serv authentication is now sent without the ":" when using the
  /NICKSERV or /NS method. #1655733.
- Added command line argument:
  --minimize=level  Begin minimized. Level 0=Normal 1=Iconified 2=Tray
- Plugin API:
  * Added "modes" to xchat_get_info(). Returns the current channel modes,
    if they are known.
  * Fixed "event_event name" for xchat_get_info() to match the docs
    exactly, but 2.8.0 (mis)behaviour works too.
- Perl
  * Execute the shutdown callback before removing the hooks so commands
    created by the script can be used in the callback.
