Updated rvmrc
Added rake task release
Fixed #1

- Removed loader_for & matcher_for methods, using a generic name_for
  helper used for naming the loader / matcher names as well as the
  instance variables used to cache the loader / matcher.
- Doing a where instead of multiple finds, so it will be just one single
  db query for lookups.
- Fixed rspec configuration to create one mockredis db for entire test
  suite run.
- Updated rake console task to also include test environment to further
  enable testing & debugging manually.
- Added require 'rspec' to spec/spec_helper.rb & moved model requires
  from spec/soulmate_rails/model_additions_spec.rb to
  spec/spec_helper.rb to facilitate rake console.
Bumped version to 0.3.0
