* first revision of vagrant configuration for standardized development on home desktops

I got this working for myself and figured i might as well commit it.  I believe it will work easily for others too, especially Mac users.  No code changes to buttonmen code, just a configuration to use vagrant to deploy a test VM containing the latest version of the code in your local repo, so everyone can experiment with it on their own machines without a lot of effort to get a webserver and database up and running.
