Merges from Scitech Branch (George Davison):

Added wxDisplayChangedEvent and triggering in MSW, when display mode changes
this event gets triggered. I don't know what should happen with other OS's
since I am not familiar with how they handle mode changes.

Watcome Version 11 now compiles with wide character support.

Fixed watcom warnings in
