Remove lockfile (ilyakatz#351)

* Remove lockfile
https://yehudakatz.com/2010/12/16/clarifying-the-roles-of-the-gemspec-and-gemfile/
The intent here is to avoid the multiple dev dependencies from raising 
security issues for consumers of the gem

* Extend work by limiting files required for bundling gem

* Add missing changelog entries
