Update Settings to Use Submenu

[Problem]
Right now, the Settings Scene uses a menu
to display the various options. The submenu
module actually works better for this.

[Solution]
Updated the Settings Scene to instead use the
submenu module, and added a nice little header
to it as well.

[Testing]
Confirmed working on device.
