- add an action menu for the selected ref in the source view
- add Add Remote, Fetch, Pull and Push buttons to the bottom bar
- Add Remote icon by Nathan Kinsinger
- Fetch, Pull and Push icons are modified versions of André Berg's icons (from 4396081c07) made a bit smaller to fit in the UI better.
- move the status message for both the history view and the commit/stage view
- all PBViewControllers now have status and isBusy properties and can use those to put a message in the bottom bar when they are the active content controller of the window
- remove the separate window toolbars from the history and commit views and create a new window toolbar in the repository window
- add new toolbars inside the history view
- new class to draw a gradient in the background of a view
- moved the search field from the main toolbar to the scope bar
This changes a bunch of ivars to __weak's, to avoid reference loops.
Furthermore, in PBGitHistoryController, we need to call [webView close],
otherwise some memory will never be freed?
