Add admin menu to configure the ATM

[21isenough]

Actual Behavior:
Currently we can only access different functions on the ATM with "multiple button presses" (e.g. button 3 times pressed, starts the Lntxbot scanning process).

Expected Behavior:
There shall be an "Admin Menu" that can be controlled with only one button. It could be a menu with all the menu points and an arrow next to the first point.

• One press on the button makes the arrow jump to the next menu point
• Two presses on the button confirm that menu point, and executes the function.

even better. maybe use some of the gpios w jumpers? so that when power on the raspi automatically know the setting? (EDIT:) guess If you want a live menu there is the same problem that it also depends on the display you choose. with a touch you wont need buttons. we could make an interface class so we can assign the buttons differently depending on display type.

Any thoughts of adding a web UI menu? Like connecting to the IP of the ATM and tweak some options from a web UI? Maybe that would be nicer to use the unique button to move or confirmation...

Let me know your thoughts.
