Add DroneHatch to fusion reactor

[RealSilverMoon]

This aim to merge fusion computers into drone control so people can enable dozens of fusion reactors with one button.
Also reduce the count requirement of input hatches (2->1), since now we have quadruple input hatch & me input hatch.

I'm not too sure about removing the 2 input hatch requirement on fusion reactors. Maybe I'm just being pedantic, but thematically I quite liked there being two input hatches.

I have nothing against adding the drone hatch of course.

This is indeed a ‘traditional structure’ passed down from GT5.08. I’m just tired of having to place a extra but meaningless hatch when using ME Input Hatch or Quadruple Input Hatch on the reactor. (And adding an unnecessary TileEntity as well)

If the quad hatches already worked for fusions then I have no objections to lowering the hatch limit
