speaker model editing is annoying

[maqifrnswa]

qms and qes changes vas, vas changes qms and qes fs, so you end up in a loop where you can't enter in values you need.

don't know yet how to fix this since you need auto-updating for consistency, otherwise you might end up with something that is impossible. maybe have "checkboxes" for "user supplied value" so auto-updater does not update? but then importing from measurements/saved files are annoying...
