Useful suggestions

Some very useful suggestions on how to extend Craft from @Seegras in fogleman/Craft#138

• I think what really would need to be done first is to implement partial blocks. Half-slabs, stairs, 1/8-slabs and so on. And torches and such. That is something I haven't the slightest clue on how to do it, yet I think is very important to have.
• Sound. Playing ogg-files would be prudent. I might be able to implement that, but right now, I have no idea on how. I'd need to read up.
• Blocks could probably be moved from item.c into some file loaded at runtime. Maybe sqlite. This would also allow builder.py to use it. This is more likely something I'd be able to implement.
• Also, an idea would be to allow it to load Minecraft resource packs. Basically they're zip-files which contain png and ogg-files. Plus sometimes localization and some text-files; but those can be ignored until needed. This way, a host of already existing textures and sounds could be used. Same with Minecraft player skins. Also, this is probably something I'd be actually able to implement.
• Better error-messages and correct user-data directories ($HOME/.craft) will be needed to. Not a problem to implement.
• I'm not that happy with the world only saved as diffs. That way, a different world generator would wreak havoc on existing builds.
• read mcedit-schematics. Probably science-fiction for now. Actually, it's probably easier to implement a filter in mcedit to read/write craft files.

Re the partial blocks and such, I've been thinking about switching from using the tile_ids struct in src/item.c to using something like faces, that actually defines how the 3d model is laid out and the textures it uses.

That said, I have no clue how to actually implement this yet, but it's something we'll need to look into if we're gonna actually get anything more complex than full blocks
