Rivtech Factory(WIP)

Start of my Rivtech facility work
-Added some new items in json parts file to make it easy to find items that have no other purpose than being parts in recipes.
-Added a new material rubber-low bashing and cut resistance, but high electrical resistance(like real life!).
-Basic factory components PLC, conveyor, hopper and industrial ammunition loader(just for decoration right now).  I think Arcadia said that he is adding heavy machinery and other factory stuff.

Not sure if I should add everything at once, or do pull requests piecemeal.  I'm rather new at using git so I'm not sure what is the standard here.
One thing I'd point out is that if you're putting out enough power to fill in for plutonium cells,  you probably don't have the juice to *also* throw bolts.
