2.5: Top Menu

* Clean up File menu, added back recover last session op.
* .blend compress now behaves a bit different, previously
  it would only respect the user preference. Now it saves
  existing files the same way they are saved, and new files
  following the user preference. The save operator has a
  Compress toggle in the file browser left panels now.

* Add menu working again, some fixes to make these operators
  work outside the 3d view were needed.
* Timeline menu removed, its contents will be moved to the
  timeline header menus.
* Game menu can now start game, changed the start game op
  to choose another 3d view if none is available.
* Render menu has a few items now.
* Help menu contains a few links again.
