[femm] AutoSave

[istokesrees@xxxxxxxxxxx]

It seems like FEMM will autosave your work if you click on Mesh or
View, presumably because these external components need to access the
file directly from the HD, so FEMM needs to write them to update them.

The problem is that this can overwrite what may just be some temporary
modifications. This just happened to me, and I lost my original model.

Is there any way around this? Could some fix be incorporated into the
next revision?

Thanks,

Ian.
