Update jwm to 2.2.2.

Changes from Relase Notes page:
http://www.joewing.net/projects/jwm/release-2.2.shtml

Changes in 2.2.1

 * JWM no longer waits for an X11 event when exiting. This fixes an issue
   where Control+C didn't cause JWM to exit immediately (issue #104).
 * Fixed a crash if a window went away while a JWM confirm dialog was active
   for the window.
 * Fixed some issues related to aspect ratios (issue #106).
 * Fixed handling of window gravity for _NET_MOVERESIZE_WINDOW.
 * Added support for XBM icons (issue #107).
 * Fixed an issue with resizing of dock icons.
 * Fixed an issue with command line argument parsing.

Changes in 2.2.2

 * More efficient handling of gradient backgrounds.
 * Fixed an issue _NET_WM_STATE not being updated (issue #109).
 * Improved the performance of moving/resizing windows.
 * Made it possible to switch desktops immediately while dragging a window if
   mod1 is pressed (issue #12).
 * Fixed an issue with windows mapping behind other windows (issue #110).
 * Fixed an issue where JWM would attempt to process the last X event multiple
   times before exiting or restarting.
 * Made newer desktop background settings override older settings.
 * Fixed a memory leak with invalid configuration files.
