Bukkit

Added possibility to create default variables for variables which contain expressions, e.g. %player%
Improved the 'is' condition to work better with variables
Made 'victim'/'damaged' work in death events
Adding a number to an undefined variable now creates it & sets it to the given number
Fixed the food level/meter to correctly use a scale from 0 to 10, not from 0 to 20
Fixed endermen and sheep printing errors when used
Fixed the 'attacker' expression which unfortunately prevents 'attacker is lava/cactus/etc.' from working anymore
Fixed error messages displaying the file name & line more than once
Fixed strings not being parsed under certain circumstances (fixes #50)
Removed 2 leftover debug messages from a past update

The default location of many block events is at an entity and vice versa. I know the cause but not how to fix this tidily.
The damage in damage events is still the raw damage, i.e. without any armour/critical/enchantment modifidicators applied.
If no world is specified in a periodical event no errors are printed if one uses the event-world (e.g. by using 'time' instead of 'time of <world>'), but it will fail silently when the script is executed.
