Proposed direction for Parrot 2

This removes Mothership as a base theme and suppresses error messages from the removal of the theme. Theme templates have been added to the Parrot templates folder. Removal of mothership has caused some features to be removed with it, namely the div killing and the class removal options. This may need to be re-implemented within Parrot. Also, it has been discussed to upgrade Susy to Susy2, so perhaps that can be added to the roadmap.
