bugfixes to WF_commodore.m / georg

updated WF_commodore.m to make it faster / georg

lupoleon - Fixed a bug while saving 2P in RoiQuest.
ROIs have the property isNew since a few commits now. Upon saving all ROIs are set to isNew=false.
There was a bug whereby if one Zlayer had no ROIs the software still wrote `ROI.isNew = false` in the empty field thus creating a struct and not a ROI object.
This failed every time a ROI method was called since it was called on a struct and not a ROI object.

calc_widefield_act.m: added compatibility for circular grid ROI during ROI length selection (previously required # ROIS >= 387)

first version of WF_commodore.m

rd: modified naming of the file if it has several acodes (before it was taking only acode of the first site)

minor /georg
