Applets/Keymap: Repaint applet on demand only

Instead of poking into the the applet window backing store whenever
the keymap changes, we now drive the GUI updates properly via
update() and paint_event().

This fixes an issue where changing the system font would cause a
"ghosting" effect in the keymap applet.
