Use the android-support-v4.jar provided by android-support-v7-appcompat
Initial change to Material Design

- Update theme attributes
- Rework settings
- Various changes needed for the usage of appcompat-v7
Make the actionbar buttons work
Cleanup and adjust margins/padding for the parcel id dialog

Only applies to API level 21 since older levels don't use material
dialogs yet. The buttons still need adjustments but this is fine for
now.
