Last commit issues
@UselessGuru @grantemsley After testing the latest commit, i've encontered the following issues while using MPH and Zergpool:

1. Excavator window doesnt get terminated. It keeps running as MPM launches another miner. Had to exclude excavator on the initial bat file.

2. Xmrig - nvidia is outdated. It must be updated to 2.5.2 because of the Monero hardfork taking place today: https://github.com/xmrig/xmrig-nvidia
It also should include the parameter "--config=config.json" so it generates the initial gpus parameters. This enables you to tweak them later, since this miner is very picky with the configurations.

3. There seems to be no yescript miner enabled for Nvidia since i cant get it benchmarked. Ive taken a look at the miner files and i havent found one (i think).

4. There are some miner logs that are getting a random 1 character per line. Will post which ones since i deleted the benchmark logs... :P

5. @UselessGuru : isnt it supposed to exist a "zergpoolcoins.ps1" pool file?

Logs attached.

Thanks.
