Subject: [PATCH] Added percentage support for block lists (untested)

e.g.
(I put block names instead of Ids as I can't remember what they are)
floor
- 90%stone
- 5%gravel
- 1%diamond
- 4%tnt

It doesn't need to add up to 100%, they are just ratios. so there is 1
part diamond to 90 parts stone. People's brains just work better when
using percentages.
