Plug the Android SDK window as the AVD manager.

- the "manager" button on the AVD selector (when not in manager
  will open the Android SDK window

- the AVD manager in the eclipse toolsbar open the Android SDK
  window as well.

Still left to do:
- remove the now obsolete AVD wizard
- figure out what to do with the other pages.
