[fixed] Lightwave export crash

[ScifiX]

The following file cannot be exported in LWO format:
https://drive.google.com/open?id=0Bx868V...2w2Vld6WEE

Export works fine in .OBJ format. Here is an output of the log window :

Thanks in advance for your support!

ScifiX, I found the problem related to exporting UV map data. For some reasons it was processing faces without UV info. (Your model seems to have some strange UV mapping).

I don't have Lightwave to test the result, so please try it and tell me if everything is OK when your project is load into it.

Got to Some fixes to be applied to v2.1.5
