Optimized zlib compression

After several years of silence, I spent 2 weeks polishing fast zlib implementation. This library got a major update at GitHub.

The code was polished, fixed all found problems. Made C-version fully functional. It generates fully identical result to Asm version. C version is just a little bit slower than Asm version. Supported 32 and 64 bit platforms (64 bit via C). Added a new test application. Test results are here. For those who wants to use this library but too lazy to build it - precompiled version is here
