I think it would be helpful if it were more obvious when a job is configured to
build a particular branch. Some ideas:

1. add a "branch" column to the dashboard (although some branch names are
so long that it might complicate formatting)

2. add a "branch" line-item on the project page

This branch info would have to be preserved on the individual build links as
well, so you'd know which branch was used for a particular build.

Currently, the only way to figure this information out is:

Hudson -> project -> configure -> branch

or read the build log for a particular build.
