Added LICENSE, updated returns for db/collection GETS, added autotest and dotfiles

Hi there - a bit of a large pull request sorry! I wanted to add some functionality to this library as I'll be using it for a Tekpub vid and I need to be able to use it with Angular JS. To that end, I needed to use the $resource bits but they don't work well with string arrays - so I changed the way GETs return list items for db and collections.

I realize this is a breaking change - but I think you'll like the resulting messages.

I also wanted to make testing a bit easier so I dropped in autotest and configured rspec a bit more idiomatically.

Finally, I added a LICENSE as code should have licenses :). If you don't like, please feel free to change.

Cheers!
