Exports UV mapping from an obj file
Now all coordinates will be mapped into the [0, 1] range, so everything will be cramped in the square. Better than a lot of details lost.

A full rework is due. No more manual parsing, I'll get some better obj parser.

(in command promt)
python uvexporter.py -i %SOURCE% [-o %OUTPUT%] [--h %HEIGHT%] [--w %WIDTH%] [-lw %LINEWIDTH%]

*-i %SOURCE% Path for your obj file. You must have this parameter or the script would not have anything to process.
*-o %OUTPUT% Path for your exported image file. If left blank, the image file will be named as the source obj file.
*--h %HEIGHT%
*--w %WIDTH% Optional output image size. By default 2048 x 2048 px.
*-lw %LINEWIDTH% Optional line width. By default 1.

Only one UVW mapped mesh per obj file, since the author didn't realise there could be multiple meshes in one obj file.
UTF-8 encoding preferred, try saving your obj as UTF-8 if some locale error pops up.
