Main change is that we now close X11 display on program exit: as this couldn't

be done in wxApp dtor (too early), a special module had to be created for it
and module dependencies added for the other modules which have to be cleaned
up while the display is still open.

Also a few minor formatting changes and removed a couple of unused variables
from wxApp.
