CEU

 WARNING: I tried to add IC2 EU support but it failed miserably. Currently IC2 EU converter does absolutely nothing, in fact it's more like to break your game so don't mess with that. Please wait more patiently until I manage to fully implement the feature.

- Reorganized config options
    - The new config file name is ceu.cfg, not gregtech_ceu.cfg. No idea why I named my file to gregtech_ceu but okay.
    - While creating ceu.cfg, the game copies the options in gregtech_ceu.cfg to ceu.cfg. well... at least it tries. So you don't need to remove gregtech_ceu.cfg and change your options again. But check ceu.cfg in case of any error.
- Added new infinite energy source/receiver
    - The new energy sources are based on GregTech machine
    - You can tweak some options from GUI. (e.g. You can toggle 'infinite energy mode' on, allowing to simply powering your base. Also you can adjust output voltage.)
    - The new energy sources now sticks to GregTech cables! Yes it didn't back then.
    - The old energy sources are gone. Well technically it's not gone, but now you can't do anything with it.
- Fixed broken UI and tooltip
- Not surprisingly, the 'GA Circuit' feature was not working. Now it should work fine. Probably.
