• Replace cat names with uid's so we can stop any form of conflict.
• Change the code to work with a uid based system

More?

I'm almost done with a config overhaul. Just a couple of things to change before I can commit, hopefully later on today.
I have used Minecraft name and meta as category names (eg. minecraft:sand:0). Seems to work perfectly but we can change it to whatever.

I can't see any possible conflict happening there so that all sounds perfect

Closed as of #50

There we go, code in my config branch (emperor06@b28b95d)

I still need to rebase before I can make a pull request but feel free to start trying it out.
