Makes SC.ToolbarView more intelligent about it's styling: not just styled appropriately for top alignment, layout adjusted to include a top or bottom border.  Also improves class documentation.
Rewrites a lot of the SproutCore TestRunner app.
- functioning again
- no longer showing experimental frameworks in the Frameworks section
- no longer unable to go back from a test
- reworked the statechart to use SC.Statechart
- removed Continuous Integration checkbox because it doesn't do anything right now
- hooked up "Reload" button to re-run a test suite without reloading the app
- fixed the routing to be able to route to sub-frameworks
