Remove .ruby-version, .rvmrc and Gemfile.lock.

Hello!

I'm not sure why those files are part of git repository.

I wanted to cross compile fat windows binaries for both x32 a x64 windows and those files are also breaking automatic build. I can remove it with some pre-scripts of course.

But I'm not keeping those files in lib. git repositories. Why? http://yehudakatz.com/2010/12/16/clarifying-the-roles-of-the-gemspec-and-gemfile/
