3D Part Preview added to Parts Tracker

[Philippe Hurbain]

Overall, works great and is damn fast! But for some reason I see nothing for this part https://www.ldraw.org/cgi-bin/ptdetail.c...44567a.dat (b version too)
Wish of the day: a 3d view button for official parts ....

Maybe it's because Orion is working on it, 44567 work fine now. But 40066 and subpart give a blank screen here...
