Add check for real player in crafting listeners

[RealGrep]

Description

The new version of reliquary is causing all patterns created to be invalid. I filed a PR there, and he said it's because AE2 needs to add a check for a player here, since it's assuming all crafting listeners are players:

The PR in question: P3pp3rF1y/Reliquary#186

Environment

• Minecraft Version: 1.10.2
• AE2 Version: rv4-alpha-3
• Forge Version: 2116
• Reliquary Version: 1.10.2-1.3.3.585
• SMP

I am seeing the same problem. I can not confirm that it is Reliquary though.

Also Chisel and Bits is having an issue with the same Tear error bug

Can confirm that guarding the referenced line with an IContainerListener instanceof EntityPlayerMP check enables patterns to work with the latest versions of Reliquary.

I'm not certain of any further ramifications though, so I won't provide a PR.
