Modular Machinery

Additions:

- Recipes can now be added via CraftTweaker scripts (documentation will follow on the MM wiki on github)

- Added the option to define oredict-item outputs (it'll select the first one in the oredict it finds. Make sure there is actually an item in that oredict entry)

- If a recipe requires energy as input and its the thing preventing the machine from working, it'll display a out-of-power message instead of "no matching recipe found"

- Machine-variables can now be used in element-arrays

- Holding shift in the Blueprint or JEI structure preview will freeze it from rotating through multiple possible blocks (in case there are multiples possible for some blocks)

- Using "R" (or whatever you defined as recipe-lookup key) on a blueprint in JEI will now also display that machine's structure preview

- The structure preview can now be popped out from the blueprint or jei preview to get a in-world preview that can be "placed down" with right-click to build it in world alongside the preview.

- There is now a "button" in the blueprint or jei structure preview showing the items needed to build the currently viewed structure/the current rotation of possible blocks for that structure

Fixes:
- Fixed 2D Item-hover when the structure is bigger than the initial scale scales for

- Fixed Outputs being deleted upon insertion in a 2nd output bus
