First Attempt At Vagrant Install & Updated Docs

Grrr minor fixes

switched to puppet supplied box, supposed to be more compatible

Updated vagrant to use different box, updated docs, made node not install on every provision.

Removed uneeded files. Fixed comments.

Updated docs, I had time to review on a plane.

Fixed PR Stuff, left out changing local.mozilla.org, could not get it to work

Fixed PR Comments: Installed dev reqs by default. Changed permissions causing problems running tests.
