script commands wildon and wildoff got mixed up

this was a mistake in the original pksv spec and tauwasser's notes
rename bit1/bit2 script commands to event/flag
if_greater_than and if_less_than commands were swapped
fix up the last few event scirpt commands
event script command 0xaa doesnt exist
use 'wait' for events instead of move effects
Merge pull request #42 from yenatch/script-commands

rename some event script commands
