Iocalfaeus Gas: Improve temperature reactions

[Erlend Åmdal]

Iocalfaeus Gas currently can only melt vanilla Stone. The gas should be able to melt more stone-like blocks, such as blocks registered as stone in the ore dictionary.

For melting stone of various types, a suggested approach is the use of a new block with a TileEntity that wraps another block. This allows better handling of the melting reaction that is currently based on many stages that should be a smoother transition. It should render an overlay texture transition on the block that should also be able to glow in the dark.

It should be possible to register block transformations at certain temperatures, such as cobblestone transforming into solid stone when near lava temperatures.

In addition, nearby blocks that can catch fire probably should do so.

Issue addressed, albeit not in the recommended fashion, in commit 4db2b88.

Tacking this on: give Iocalfaeus the ability to do in-world smelting. (ex: sand -> glass, cobble -> smooth stone). This ties in closely with this issue, in particular registering block transformations.
