Provide humanly derivable URL to branch builds.

When our Bamboo instance is under high load and the UI is struggling, I often like to cheat, take advantage of Bamboo's predictable URLs, and go straight to wherever I'm going.

Currently in my team we're using too many branch builds, so if I want to go to a branch build I usually have to go to a few intermediary screens to actually get there. It would be nice if I could just go straight to the screen by cheating and adding the URL, but the URLs for branch builds are unguessable.

Please add a ?branch="branch-name" parameter that redirects to the URL for a given branch.
