Infinite Energy Emitter (from CEU)

[bruberu]

What:
This particular PR addresses an issue in testing where it is often difficult to test certain machines and recipes without a singleblock energy source, which becomes an especially pronounced problem for the higher tiers.

How solved:
To address this, I have imported the Infinite GTEU Energy Emitter from CEU. For the most part, this implementation was copied entirely, although I did decide to do a little refactoring with the GUI builder, since I could not find an easy way to work around it. Later on, the code there should probably be cleaned up, although I do not have the skills to pull off such a thing. Furthermore, a rather large excess of extraneous classes, used for the rest of CEU's infinite energy handling tile entities, have also been imported, to serve both the purpose of leaving the door open for importing the rest in, and to serve the purpose of making this less of a headache for me to handle.

Outcome:
Adds a new MTE for infinite GTEU generation.

Possible compatibility issue:
None are expected.
