Metallurgy (Now with 100% more OP workshops!)

BETA - use at your own risk, this is my first time screwing around in DF raws beyond the usual 'time to make sandy loam count as sand because I'm lazy'.

The mod currently adds two workshops, both for ore/metal processing, both more efficient than 'vanilla' recipes.

The 5x3 Ore Grinder is designed to, well, grind ores.
It won't quite double them but it is guaranteed to increase yield on average.
It produces 'processed' boulders of 'pure' metal ore at about 1.6x
Output depends on the 'quality' of ore it's fed, with some (e.g. tetrahedrite) likely to also produce by-products.

There's also a (probably even less balanced) recipe for grinding bones down into a flux stone.
Which is even less realistic, but these are DWARVES we're talking about here; Armok is no doubt pleased by grinding down bones into true dorf steel.

The 5x5 Blast Furnace is designed for your pig iron & steel needs.
Meant to be representative of an 'industrial' blast furnace.
It is very efficient in flux- and fuel-costs for making pig iron, and more efficient flux-wise for steel.
The 'downside' is the large batch sizes (6 processed iron boulders for pig iron, or 4+4 iron + pig iron for steel)

This is definitely beyond 'normal' balance, like it says it increases ore/metal yield for a relatively small amount of effort & building cost.
In the future I'd like to expand on the metallurgy aspect - dwarves with bessemer steel furnaces??? - and probably increase the effort involved in actually getting increased yields like this.

Since this adds reactions (recipes), buildings and mats, new worlds will be needed to actually get any updated features.
And of course you can only *add* a mod to a new world as well.
Please leave comments etc. on desired features. It's pretty barebones at the moment.
I am aware of some graphics issues (namely grey pixels on the blast furnace) but until I can find a good guide for how the material-colouring actually works for workshop sprites I'm kinda in the dark on fixing it.
For now if it bothers you (kinda looks like smoke??) I'd recommend building these from grey-ish materials.
