THRIFT-276. rb: Ruby libraries should have one class per file

This monster of a patch moves all the classes into their own files and specs as appropriate. Additionally, it concentrates all the requires into thrift.rb, removing the need to require any other file. (Changes were made to the compiler to reflect this reduced requirement.)
