* Handle preference fragments using the framework
The previous code started new preference "screens" as activities, even though
each one hosted a single fragment.
Modify this to use the framework's support for swapping in/out different
preference fragments.
PreferencesActivity:
- Remove the code for launching tab and proxy preferences
- Remove the code for setting titles, each fragment is responsible for that
- Implement OnPreferenceStartFragmentCallback to swap fragments in/out with
the correct animation
PreferencesFragment:
- Use `fragment` property instead of `setOnPreferenceClickListener`
- Set the activity title when resuming
Everything else:
- Set the activity title when resuming

* move preference related to to dedicated preference package
* update proguard-rules.pro
