Checkout:
- PBGitRepository: add checkoutRefish:
- PBRefController: renamed checkoutRef: to checkout: and use new method in PBGitRepository
- add to the contextual menus for commits (it was already in the menu for refs)
- add "Checkout branch" checkbox to the Create Branch sheet
- store the state in the defaults
- tell the commitController to rearrangeObjects so that the refs highlight correctly (seems to only be a problem when going from a branch to a detached HEAD at the same commit)
We don't want to do this in the commit view, as that way you can't
commit whitespace differences. You'll never be able to have a clean
working tree, and you can't see why the files remain 'unstaged'. So, we do this
only for the history view :)
Since Git recommends to use 50 characters in the first line of a commit
message, this adds a vertical line to the commit message view to show where
the 50 char limit is.
[PB: This preference can be changed using a user default -- for now we don't
have a preference pane yet, so this is hidden.]
