Merge lp:~eday/burrow/bootstrap into lp:~burrow-core/burrow/cactus

[Eric Day]

Created initial OTP application and supervisor skeleton. Also includes README and configuration for building releases.

[Vish Ishaya (vishvananda)]

Is there any reason to go through the approval process for the first few releases? It seems like overkill if you are the only one currently committing code. That said, i branched and ran the coverage tests and managed to start the application so that is an lgtm from me.

review: Approve

[Eric Day (eday)]

I think there is still value in it to make sure I'm not screwing anything up. I can just commit straight to trunk and ping you guys if you'd rather not use this process though. :)
