Switched to bundler layout

So in the process of trying to fix the asset pipeline issue I rewrote the entire gem using bundler. It's a lot cleaner.

If you'd like merge this one and close the other. But at least merge one. :)

Here are some comments on the changes:

.gitignore: Gemfile.lock should be ignored for gems (See Yehuda Katz post on this). Also system files (.DS_Store) should be ignored at a global (system) level
Gemfile: Should use the SSL version of rubygems
VERSION: Is redundant; Added a centralized location for gem version
Gemspec: should include railties as a dependency
