Aborting trigger when different modes are selected

[prasimix]

If for example ch2 trigger is set to FIXed, and ch1 to LIST, switching off ch2 (OUTP OFF) will stop LIST execution on the ch1. There is not need for such behavior despite the fact that single triggering system is used for controlling both channels. Therefore only if channel is in STEP or LIST mode should affect output of other channel when switched off.

Partially resolved. There is no need that channel's voltage and current output set values stays disabled when channel output is turned off.

It's now enabled, but keypad page cannot be entered. Also if encoder confirmation mode is selected it's possible now to "intrude" other channel's (ch1 in our example) output value settings.
