should probably add a -1 to that enum and other small fixes

patrol code based on Ufopaedia data

see http://www.ufopaedia.org/index.php?title=ROUTES.DAT
"flags" now used to direct aliens other than scouts
seems to work great in UFOs but not in Final Assault (commanders roam whole

don't make everyone scouts in base assaults!
better patrol behavior

aliens prefer to move when standing in fire
fixed the module targeting in xcom base defense; _flags rather than _reserved
is set to 5 for nodes where xcom property is to be vandalized
