Bounty - Ability to map additional instance of a button to a seperate GPIO pin

[TheTrainGoes]

Currently you cannot assign multiple instances of a button to different GPIO pins.

As an example, with UP mapped to GPIO2, I cannot add an additional instance of UP to GPIO22.

This would be an add-on that can be configured in the web-ui.

The first section would let you specify the GPIO that the additional button is hooked up to.
The section section would let you specify which button has the additional instance of assignment.

As an example, you may choose to assign UP to GPIO22, or P1 or even START.

This has been implemented - thanks @deeebug !
