* Added a basic tool tip API, and implementation.

* The BView API can probably be regarded as good enough; the implementation
  might need to be improved over time (also, some things as archivability
  aren't fully implemented yet). The ToolTip.h header should get public once
  finalized.
* Added new B_MOUSE_IDLE message that is sent to a BView after a certain
  time has passed (BToolTipManager::ShowDelay()).
* Added small test app (ToolTipTest) that shows what is already working.
