Android: Add import/export options for user data

Browse source 
Apparently there are phones where accessing Dolphin's app-specific
directory isn't just annoyingly hard but actually impossible.
To give users of those phones at least some kind of way to manage
their data (even if it's a lot less convenient than if we were
allowed to let the user open the app-specific directory in a
file manager), I'm adding a way to export the directory to a
zip file and then import it back.
