Issue Description:

Having a FloodLight connected to Ender IO Electrical conduit causes a crash when on latest version of Ender IO

What happens:

Loading map crashes when EnderIO tries to SetNetwork->getPowerInterface -> getCapability on a Floodlight connected via Ender IO Electric Conduits.

Since this happened on an upgrade I'm unsure the behavior when placing it in game.

What you expected to happen:

The map should load successfly

Steps to reproduce:

1. Connect a Floodlights Floodlight (https://mods.curse.com/mc-mods/minecraft/224728-floodlights#other-downloads) to an Ender IO Network and power it.
2. Load the game (though it might crash on placing?)
   3.
   ...

Affected Versions (Do not use "latest"):

Minecraft Version: 1.10.2
Minecraft Forge

Ender IO

That's Floodlights' fault, they have a hard dependency on Tesla they don't declare.
