[support/feature request] adjust the GC length from the GUI

[julou]

What is the current way to set the length of the GC that is analysed?
I guess it requires to use a parameter file, not so clear which one yet (probably highlighting the need for #4)

Explanation:
Minor annoying issue.
Right now, if one loads a GC into MoMA, and notices that the length of the GC does not really match what is in the picture, there is no way in the GUI to change the length of the GC, i.e. one would have to quit MoMA, then start again after changing the parameter.

The reason for this is that MoMA computes a bunch of things upon startup that depend on given GC start and endpoints. If one would change these values from within MoMA, I would essentially restart it anyhow. This said, there is currently no auto-restart and it would have to be implemented.
