* Complete rewrite of mcc.  We're now plugin based
  where plugins are dynamically detected upon loading.
* Setup translation system based on python-distutils-extra instead.
* debian/control:
  - Clean up depends which should now be on mythbuntu-common.
* debian/links:
  - Drop, no longer necessary since all plugins are in common
