Doozer 0.1.5 Released

I added project configuration support for loading a specific Doozer gem version this evening.

All you need to do is declare the version of the gem your project requires and it automatically loads it for you. This is facilitated from 'config/boot.rb' which handles the loading. I have one small change which isn't committed to load 'grippy-doozer' (github gem version) if it exists. I'll commit this with the next patch.

Next up: Turn some of the project generator templates into Erb files to make them easier to maintain.
