Thomas Goyne 123f02f0fb Process hotkeys in wxEVT_CHAR_HOOK rather than wxEVT_KEY_DOWN 
Char hook events propagate by default, removing the need for the event
filter to make key down events propagate, which was causing some funny
issues.

On Windows, the char hook handler runs before menu accelerators, fixing
a bug where Default context hotkeys would override more specific ones
when they appeared on a menu. Unfortunately, this is not the case on
GTK, so the dumb accelerator-disabling hack is still required.

Originally committed to SVN as r6724.
