Merge lp:~wgrant/launchpad/gitcrumbs into lp:launchpad

[William Grant]

Give Git repositories and refs more sensible breadcrumbs.

Give Git repositories and refs more sensible breadcrumbs:

 Git >> lp:~wgrant/launchpad >> master

I considered allowing navigation to PersonProduct via something like:

 Git >> William Grant >> launchpad >> master

... but that makes things longer for default repositories.
