Merge lp:~barry/bzr-builddeb/609186-urls into lp:bzr-builddeb

[Barry Warsaw]

This branch implements the easy part of bug 609186. It provides ubuntu: and debian: url schemes (and u: and d: shortcuts) for getting at source branches in Launchpad. It doesn't do the fancier stuff suggested in the bug - that's for another time.
