Install Ruby messages on versioned directory

Description

As of pull request #47 (released first into ign-msgs3), ruby messages are being installed at an unversioned directory, i.e. lib/ruby/ignition/cmdmsgs3.rb in my local install. It looks like the debs aren't installing them though. We noticed the problem while trying to create homebrew bottles for ign-msgs4, and the files are conflicting.

Steps to Reproduce

1. Install ign-msgs3
2. Install default

Expected behavior:

They should be installed side-by-side in versioned directories. I don't know how these files are being used, so I'm not sure what the appropriate directory structure would be. cc @nkoenig

Actual behavior:

The *_pb.rb messages are overwritten.

Versions

ign-msgs3 and default

Additional Information

For now, we're making the bottles for v3 and v4 conflict, so they're not side-by-side installable.
