Add Ruby 2.0.0 to Travis config

The indexes for the PID were off by such that if you tried to call
a field like patient_dob you would get the value for previous element.

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.

sure there is an open PR about this, that just goes and modifies
the list by hand.
Remove support for RBX.

Add some rbx love back in.

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