Issue Description:

I do hope that you don't mind this question or feature request.

Is it possible to filter Soul Vials, like just allow Soul Vials with Zombies to pass through? I guess that this would be filtering data on NBT fields. I've searched and not found any hints is this is possible.

I would like to automate making crystals and catching Enderman, Zombies is not a problem using a powered spawner and a mechanical user, feeding XP into the Soul Binder is not a problem using an Ender Tank in push mode.

Affected Versions (Do not use "latest"):

• EnderIO: 1.10.2-3.1.183
• EnderCore: 1.10.2-0.4.1.65-beta
• Minecraft: 1.10.2
• Forge: 12.18.3.2254

EpicSquid, a "mob type" filter for our vials, broken and powered spawners would be nice. Those all use the same NBT/tool class.

The powered spawner can spawn directly into a soul vial ...

That's awesome! Helps a lot.

Filter would be nice too.

Will look into it. Should be simple enough.
