Fixed keyboard navigation; it should now behave pretty much like R5 AFAICT:

Browse Source 
- moved standard keyboard navigation into the BView::KeyDown() hook
- the window now only handles tab+option/command key
- B_COMMAND_KEY triggers group jumping, not B_CONTROL_KEY (that activates the switcher,
  but directly in the app_server)
- fixed broken group navigation: (modifiers & B_COMMAND_KEY & B_SHIFT_KEY) is different
  to (modifiers & (B_COMMAND_KEY | B_SHIFT_KEY)) and is just never true with these
  constants.
That allows the tab key completion to be used again in Terminal.
