Persist 'Controllers Allowed' setting (#86)

When using Virtual Desktop toggling performance overlay (both thumbsticks down on VR controllers) disconnects gamepad in some games.

This patch allows to write state of 'Debug->Controllers Allowed' setting to config.txt making a workaround in game profile possible.

VR.is_using_controllers_within() was not respecting the setting making gamepad disconnect on game exit. This is also fixed.
