Some GUI Feature ideas

[lnies]

As discussed, some features for the GUI / daemon

1. Add y error bar to parameter scan (maybe only for the count rate scans where you can easily assign the error as SQRT(n)
2. Make data input for "Rate Statistic" plot arbitrary to be able to choose between the different timing inputs (AND, XOR, DISCR1, DISCR2, etc...)
3. Selection of trigger signal input for ADC sampling "trigger_input" in /muondetector/muondetector.conf only lists 0 - XOR and 1 - AND. Can other trigger inputs be chosen here? Maybe add comments in the config to highlight the available options

Nr 3. is implemented with commit 5f74db0
