Added local stuff to make the app work.
Added missing console-io dependency.
Added git_project_name field to assignments.
Added branch name to commits.
Added the status and results fields to builds.
Removal of unused field.  Not sure why this appeared now.
Added clone_url field to commits.  Not technically required, but this avoids the need to perform a join and dynamically recompute it.
Backend now connected to Ruby.  Ruby side is beyond hacky, but this can be cleaned up later.
