Make the buildables list a little nicer.

Summary:
Depends on D7501.

This just renders the buildable's actual object name onto the list, so you can see at a glance what the buildable represents.  I'd like to also pull across a list of builds of this buildable and change the bar color, but I'm not quite sure how to do that in the search architecture without N+1 querying.

Test Plan:
Looked at the buildable list and it looked like this:

{F78555}
