Multiple assignment is inconsistent when the first value is also the default

[wojtryb]

GUI allows to set the first value be the same as the default one. After the reset with a long press, next short press switches from the user perspective does nothing, as the value is being changed from the default to the first one (which are the same).

This is a design issue. Probably multiple assignment template needs to be rewritten:

• do not support multiple occurrences of the same value in the list (as the GUI do not allow it anyway)
• with each key press, check if the current value is in the list. When it does, switch to the next one, if not, activate the first one. (this changes how the feature behaves from the user perspective)
