Removed actionbarsherlock hack. Replaced with appcompat

Removed the actionbarsherlock code and replaced it with appcompat. This doesn't include any of the material design styles Google just put in the support library but does get rid of the dependency from a long deprecated library.
So for some reason when I wrote all these strings a long time ago I wanted them to all be lowercase... I'm not sure why. Anyhow would be good to eventually capitalize them the same way
