Start work on scalding-lingual support.

Lingual has some nice features that would be nice to have for some small adhoc jobs and especially with the Scalding REPL.  These changes do not contain the repl code yet(coming in a future pull request) but attempt make lingual a bit easier to use with Scalding libraries and allow for scalding code to still be written and run with a Lingual job.

This code also does not support nested functions yet in queries like thrift.  Should be technically possible based on conversations with the Lingual team.


No where yet, I originally wrote this code to work as a normal Job and also in the REPL.  This code was a remnant of the REPL code that I didn't refactor out.  I am going to do a pull request for the repl code after this gets in so I figured maybe I should leave it for now.

I can remove for now if you think that is a good idea.
