Compiler optimizations. Optimised pthreads. Should be at least as fast as the current nheqminer, ideally a fraction faster.

Feel free to check it out, but this might be premature for a pull request - this a work in progress at the moment.

Single static file and static library to help prevent dll replacement and make installation easy

Included optimised pthreads. Next step is to look at the actual code itself and see what can be done (profiling to see if there are any easy wins).

I've only been testing under windows. Not even tried to compile under Linux or OSX yet. The screensaver code is all empty shells at this point. Need to link it to the 'goldminer' lib still and finish the automine algorithm that will pick the best CPU/GPU config.

@DrMiaow This freaked me out. Perfect!
