Converts LDraw model files to OBJ.
What needs to be done:
1: Custom color support, for example color #432112. a) add Color object to store value till it is ready to be written into mtl file. b) it should create .mtl for custom colors, but only if there is actual custom colors. Ldrawcolors.mtl is for standard ldraw colors.
2:) Remove useless project from source. I refactored in middle of development to make it function better but left now useless files.
