Update import_ldraw_ng.py

• merging works as it should now
• added materials (not previously implemented)

The importer fails with Blender 2.70a. My Snowspeeder reports some errors and another smaller model looks messed up (geometry, colors, smoothing).

@virtualrepublic I am using 2.70a too and here it works OK (but actually test just shortly with very simple 4 bricks model), can you post/send me your model to see what errors it giving?

also you should know that this code is still just in development rewriten from scratch by other guys and I only added or better said implemented color schema from previous old script v1.1.5 that works for me as I said above + as for the merging I also noticed something wrong with new code cos it left out some part it should not so guys needs to tweak it furthermore, so... ;)

except that I am actually at the same time (or better said now only) working on new version of old v1.1.5implementing right rotation values in Blender GUI where again I already succeded with simple 4 bricks test model but when I load normal big model it messed up giving few errors that I am working on them now... :)

@bublible Thanks for the PR. I'm a bit swamped right now so I can't look at it yet, but hopefully I can soon. Word of advice, though, for future reference and to help you out later on: If you had to use a hack to make it work, that's OK (although if you can provide details we can try to figure out why you have to bypass the menu item to begin with), but always remove it before your first commit so it does not end up as part of the PR. That's a sure-fire way to not have your changes (even good ones) merged as-is. 😉
