Console version should have a 'tweakables' UI

[walbourn]

The current control scheme for Xbox is all based on direct-mapping of the gamepad except for the file selection.

There are no too many controls for this, so I should switch to a simple UI for controlling the various toggles, and remove them from direct-mapped. Give the View key is exit and the Menu key is select file, probably the Y button should bring up the UI and then DPAD/A/B is used to drive it.
