Update version: 1.7.5.15-mod

Changelog:

• Added Dual mining for more profit (DaggerSia, DaggerPascal, DaggerLbry and DaggerDecred) for Nvidia cards (I haven't tested AMD cards)
• Updated ClaymoreAMD_Dual miner to 9.4 to support Sia dual mining. (Make sure to download the 3rdpartyminers.zip)
• Revert "Graceful shutdown" commit from original repo, it causes more issues than it fixes
• Fix Lyra2REv2 Algorithm returning crazy ass numbers (i.e: 2000 USD/day)
• Debug console cleanup with a good looking profit table (http://imgur.com/a/JqQoD)
