Adding a (new) working formula for the last version of cgminer.

cgminer is an open source Bitcoin miner. It handles mining on CPU, GPU,
FPGA as well as OpenCL acceleration. It is written in C/ASM and is
maintained by ckolivas on GitHub. It is one of the main miner around.

I updated Kaelten's formula to cgminer 2.10.5 (last version), and it works now.
