Changed some of the preferences to reflect their functional state. Changed the source code link and title to be accurate. Changed the EditFeedDialog buttons to use a StateListDrawable similar to the Holo Light default. Changed the Activity theme to be Holo.Light.DarkActionBar instead of a custom one with a transparent background. This makes things a bit neater and fixes the PreferenceFragment's children being transparent.
Removed a library that was not needed.
