keyboard/focus handling improved a bit more:

1. wxFrame doesn't give focus to anything at all on activation
2. last control restored more often (some problems still persist)
3. buttons process enter
4. text controls with wxTE_PROCESS_TAB still leave TAB work as dialog
   navigation key if the event wasn't processed
