Alchemic Ash

Full documentation on this update will hopefully be up tonight (Friday the 23rd).  In the meantime, here are the changes in plain test:

1. Gunpowder is now a furnace fuel, burning for ten seconds (one smelt).

2. Wands are once again pretty decent melee weapons, causing enemies struck with them to catch fire; the stronger the wand, the greater the fire damage.  They still lack right-click powers at present, however.

3. You can again duplicate singing stones.  Surround a singing stone with 8 quartz in the crafting grid, and pull out a duplicate without using up the original.

4. The Ash Smith is now the Ash Feeder; such blocks already in worlds will change to this.  To use an ash feeder, park a hopper under it (touching the bottom of the feeder; no gap).  Every ten seconds, an alchemical ash (item) will be produced inside the block, which the hopper can then suck out.  Stick that pairing on top of a furnace, and it's infinitely supplied.  It can still be used to craft everything the Ash Smith could.

5. The Blast Smith is now the Powder Feeder; such blocks already in worlds will change to this.  This functions as the ash feeder, but supplies gunpowder.  Since gunpowder is now a fuel, you can thus plug a powder feeder into the side/back of a furnace to fuel it infinitely.  Additionally, you now use an ash feeder, rather than a cinder(?  whatever) smith to craft it.

6. The Sand Spitter is now the Sand Feeder.  Same deal.

7. Since hoppers are now pretty fundamental, a new hopper recipe has been added: Swap out the iron ingots in a normal hopper recipe for ash bricks (the items), get hopper.

.........

For those following the mod long-term, please note:

Over future updates, the cinder/blaze/inferno smiths will be replaced or orphaned (recipes removed).  Multi-part feeder/hopper/furnace/hopper machines using the blocks introduced here will be moving to the centre stage of "infinite resource engines" as development continues.  

So, if you're currently running with the core smith as a central feature of your playthrough, or building towards them, you may want to build up a nice stock of bales or start engineering such a machine now; this is your "transitional" update.
