- weighted cuda compressor.

- faster and better BC3n compressor
- add normal map flag to DDS files that store normal maps.
- stop using RXGB fourcc code.
- move tools to tools/
- add temptative config dialog for UI based tool. 
- add experimental normal map mipmap generation.
- start adding support for input dds files in nvcompress.
- many other small fixes and cleanup.
