Skript

Added expression 'UUID of %player/world%'
Fixed all negated conditions when 'or' or 'and' is used after the condition, e.g. 'a is not x or y'

Fixed an error related to commands in the newer Bukkit builds
Fixed Skript not working on Bukkit version older than 1.7.2 R0.4
Fixed an error in 'on stepping on a pressure plate'
Added british spelling 'metre'
Likely fixed world guard regions looping too many blocks
Fixed expression lists loosing their type sometimes
