Hide not mapped branches

[gusarov]

We have 40 branches (7 years of releases and set of feature branches). Usually only 2-4 of them are mapped. It is really not easy to pick a proper branch that is mapped. This might be done optionally or via some kind of quick filter button.

It would be great if cloaked or unmapped branches were hidden or at least put at the bottom of the list.
I had to delete old branches to get them off the list, which is extreme (even though they can be undeleted).

When working with feature branches it went to be terrible finding the right one.
