It seems that the xxxhdpi `active` drawable was corrupted. The old
build tools could still read the drawable, but the new ones
couldn't handle it. Regenerating the drawable fixed the crash.
Also removed `inactive` drawables and xml drawable which weren't
being used.
Made actionmode bar overlay the toolbar.
Updated UI for device edit/create fragment to match the folder one.
Refactored FolderFragment to match DeviceFragment.
Improvements for Details styles and item heights.
