Open source (== NO HIDDEN MININGS) version of X11/X13 algo sgminer with separate kernels.

Upd. 2014-06-03

Fix x13mod for AMD HD 5xxx/6xxx cards. Use for these cards "kernel" : "x13modold" in config file or -k x13modold from the command line. All parameters (intensity, threads etc) need to be tuned individually.
A little improvement in hamsi kernel.
Further fixes and improvements will be committed to innovative sgminer 5 only: https://github.com/sgminer-dev/sgminer/tree/v5_0.

Added x13mod (Marucoin, Boostcoin etc) support
Increased time to SICK state
Experimental: hashbuffer allocation depends of initial {i, xi, rawi}ntensity. Maybe increase a stability, maybe not...

Mainly thanks, obviously, girino for his brilliant idea.

Thanks to Elun for actual Windows binaries.

Thanks to Remember remember the 5th of November for extracting kernels file from "girino's 2% fee version miner" and providing Windows binaries.

Increased time to SICK state (WTF? - read https://bitcointalk.org/index.php?topic=623409.msg6949113#msg6949113)

## Mod x11 (separate kernels)

0. Use "kernel" : "x11mod" in config file or -k x11mod via command line.
1. In case of instability please set a little bit lower engine frequency than a original sgminer.

Do not hesitate to donate

Thanks for all.
Good mining )
