V0.3.7
+ 'kadena' algorithm huge hashrate increase
+ Added 'gpu_' prefix to GPU related parameters in config file : gpu_intensity, gpu_raw_intensity, gpu_worksize, gpu_threads, gpu_tweak_profile, gpu_target_temperature, gpu_shutdown_temperature, gpu_off_temperature. 'gpu_conf' parameters naming stays the same.
+ Added new parameters in config file : cpu_threads, cpu_affinity, cpu_priority
+ Renamed 'pool_use_tls' in pool configuration file to 'tls'

- Kadena algo is now again profitable to mine with GPU (at least for some time), so try it out!

- From this version i added the gpu_ prefix to all parameters in configuration file that are related to GPU, and used outside gpu_conf. Parameters inside 'gpu_conf' stayed the same.

- Also added possibility to set basic CPU parameters in configuration file ( cpu_threads, cpu_affinity, cpu_priority )
