Lots of progress with dynamic theming, the nav drawer now uses a RecyclerView, AboutDeveloperDialogHelper is now a DialogFragment, RTL support (to suppress Lint warnings), other various small fixes, cleaned up and formatted lot of code (and removed un-used resources), R.string.ok > android.R.string.ok, R.string.cancel > android.R.string.cancel, switched dialog helpers to DialogFragments.
