Add Ruby 2.0.0 to Travis config

This commit fixes this issue and adds a full test for all values of a PID.
Require files in gemspec via git, upgrade Rake dep.

The minimum rake requirement should be at least version 10.0.0 as
there are some security issues associated with the earlier versions.

the list by hand.

Add some rbx love back in.

Because some people use it and it's not that difficult.
