No progress display, so it's UX sucks, but it works.
Need to add a progress display, so the user knows it's not just lost in the weeds. Either a neutral 'working' progress bar, or (optimally) some cool thing that feeds off the pipe and fills a text display.
This changes a lot of code, so quick review:
* RepositoryDocumentController now returns the document without selecting a ref
* PBGitWindowController now optionally shows the default view, or selects no view at all
* PBGitRepository keeps a pointer to its WindowController so that it can change views
Multiple repositories can now be opened by using the File → Open… menu option.
Each document is a PBGitRepository with a PBDetailController controlling the window. PBRepositoryDocumentController is the document controller.
When launched, the application will attempt to open a repository with the current directory as its path. If this fails it will display an open panel to allow the user to select one.
