Android: Add "more settings" button to overlay control setting dialog

Some people might wonder where the ability to select an extension
and the Sideways Wii Remote went. This button will take them to the
general settings, which is where those settings now live.

At some point in the future, we should probably move everything to the
general settings. But this pull request is already big enough as it is!
