[LDCad] Dropping Frame Rate when MPD View is open in Part Bin

[Gerald Lasser]

It currently invalidates all depended renderings whenever something changes (new part,part move,color change, etc).

But I guess I could add some kind of option to disable real-time updates for part bin cells, I will look into it.

Thanks for considering it.

It is basically working for me now as I know what to do, respectively watch which bin is open, but till I reached that point :-)
