Title: Feature/automatically cleanup build files

Upon every change on the repository, integrity app pulls the latest
commit and stores it on filesystem. From time to time, releases will
start to accumulate. This feature allows integrity to clean up their
builds through 2 methods:
- Upon explicitly deleting 1 build through the web interface
- Through a cron job each erases all builds before 5 days ago

Changes:
- Hook on Build model after destroy to clean up build folder on
filesystem
- Add existing task to clean up old builds
- Create new task to clean up zombie builds folder which reference
previously deleted builds
