Fix dependencies

* Do not specify dependencies in Gemfile (this is a gem)
  * rake was already in gemspec causing bundler to complain
  * added package_cloud to gemspec
* Change `mysql` to `mysql2` because `mysql` is so ancient it won't even compile
* Add Gemfile.lock - this is now considered best practice: rubygems/bundler#6184
