This updates the repository list to have helpful action links for

getting RBTools configured against that repository. When the admin

clicks "RBTools Setup", it will pop up a modal dialog box showing the

setup instructions for that given repository.
To make room for the new column, I've also shortened the label for the

"Show this repository" column in the repository list. Upcoming changes

will add new actions to this list.

Tested this link with several different repositories, and saw the expected

text.
