Update gem attribution information
Remove default dependencies

- While documentation and testing stratedy not defined don't bother with
  extra dependencies
Ignore Gemfile.lock and use rbenv for ruby version

- Initial gem version at 0.0.0
- Since most of our projects seem to require Rails ~> 3.2.0 we should
  use Ruby 1.9 as our baseline supported version
- Considered bad practice to include Gemfile.lock in a gem
