DEBUGGER: Simplify how our console debugger works / is used

* Remove _isAttached member var and isAttached method
* Engines now always call the onFrame method; whether it does
  something is decided by the debugger class resp. its subclasses
* Make detach() protected instead of private, so that subclasses
  can invoke it
* Remove _detach_now member var (call detach() instead).
* Rename _frame_countdown to _frameCountdown and properly
  document it.
* Add more doxygen comments
* Cleanup
