Add nuclear reactor

Still needs some work. I am pushing it to get ideas and feedback.
Also fix some bugs in the LV coal generator that were found while making
the nuclear reactor.

Conflicts:
	technic/init.lua
Update nuclear_reactor_hv.lua

Fix temporary recipe.
Move files to subfolders
Load tools
Remove file that doesn't seem to have any use.
Fix typing error in register... file
Fix two issues with nuclear reactor and set the burn time to 24h.
Fix forcefield
Add LuaVoxelManip support to forcefield
Fix coding style of nuclear reactor
Fix code style of the high voltage battery box
Gigh -> High
Remove deafault creative mod dependency.
Fix crafting recipes and some code style.
Blast resistant concrete (by ObKo)
New items by ObKo
New items by ObKo (textures)
Add compressor
32x compressor textures
LV batbox background
Add compressing method to UI
Remove lv, mv, and hv tiers from power tools.
Theyre already tiered with Mk1-3 (at least drill is, more in the future).
Tools can be considered as designed for different tiers of circuits thx to their power needs.
For example Mk3 will require ages to load in LV batbox.
Batboxes load tools timining: LV standard (1000EU), MV 4x faster (4000EU), HV 16x faster (16000EU)
Also since 1EU is the same in any circuit it is possible to move energy from one to another with portable devices like crystals.

Other changes:
- moved charge/discharge functions to battery_boxes_commons.lua
- added UI style backgrounds for all the batboxes
