[Fluxus] obj loading speed

good idea! i did this and the loading time dropped to 1.4 seconds. the 
file size increased from 1.2mb to 4.8mb, so now only basically line 
processing and tokenization take time. with a 3.8mb obj file the loading 
time was about 30 seconds, with the optimized version it went down to 16 
seconds, and now it's about 4.3 seconds if all the indices are the same 
(file size increased to 15megs).

as far as i know, you are right, opengl needs unified indices.

best,
