Repeated simulations in OMEdit

[massimo ceraolo]

I appreciate the Re-simulate feature of OMEdit a lot.
changing parameters and re-simulating is common and effective.

However the same file is always re-written, because in the re-simulate setup dialog box the file name cannot be changed.
In case that file made is made modifiable, I think, it would be very easy to make parametric studies and comparing results from different parameter values on the same plots.
