DXT1n format #21

Add support for normal map encoding using DXT1. The quality is poor, but on
some hardware DXT1 has great advantages over DXT5.

This can be achieve already setting the color weighs to (1, 1, 0), however a 
custom
compressor that only fits two components would be much faster, specially in 
CUDA and
in the non vectorized CPU version.

I've added DXT1n and CTX1 compressors implemented using CUDA. CPU 
implementations
will follow later.
