Title: Add theming, with a Dark and Light theme

- The light theme remains the default, and should look identical to before
- Modify the layouts to reference colors in the theme
- Add an option to change the theme in the preferences (note that this does
not take effect in already running activities)
- Modifiy the ConversationActivity as the secure drawable for the action bar
is not handled in the layout
- Modify ConversationFragment as the text color is not handled in the layout
- Add calls to setTheme in the activities
