Added Specky for rspec highlighting outside spec/

If you have rspecs anywhere else (say fast_spec/), the
default rails.vim highlighting doesn't affect them. Added
Specky to do this. Specky is not currently enabled in any other
way (we will still use ruby-vim-conque to run tests, but Specky
will do highlighting/file detection).
