Foxy-Miner v1.18.0

Changelog:

• Use fixed indexes for multi miner setups. This means if you run a multi miner setup and have one miner disabled the other miners endpoints are still counted as if it were enabled, the index is just skipped. This can be a breaking change, please adjust your miner config accordingly.
• Add support for auto-downloading a Mac OS X compiled scavenger 1.7.8 binary
• Remove DISC from the first run wizard as well as the profitability service
• Use the foxypool.io domain
