New vehicle parts: FOODCO kitchen buddy and mounted electric forge  (WIP, don't merge yet)

For those who just aren't satisfied with the RV kitchen unit for their cooking needs, I give you the FOODCO kitchen buddy!  A tribute to all those crazy kitchen gadgets they sell on TV at 3 in the morning, the kitchen buddy provides you with a water purifier, vacuum sealer, dehydrator, and for some bizarre reason, an ammo press, all powered by your vehicle's storage battery!  Not available in stores, the kitchen buddy can be built from a set of plans tucked into the fabrication textbook.

Also, I'm working on typing up a mounted electric forge, so you can just weld the forge you have to your vehicle, and power it off the storage battery instead of trying to dig up huge piles of batteries for the thing.

Finally, I did a little rebalancing on the weight, volume, and components of the vehicle welding rig.  Looking back, basing all this stuff on the RV kitchen unit was a bad idea, because the kitchen unit is about 10x as big as all it's components put together, which is ridiculous.
