patrol code based on Ufopaedia data

"flags" now used to direct aliens other than scouts
seems to work great in UFOs but not in Final Assault (commanders roam whole
base)
don't make everyone scouts in base assaults!
better patrol behavior

aliens prefer to move to nodes with their equivalent rank, like xcom1
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
cleanup, fix xcom property targeting for vandalism
Revert "cleanup, fix xcom property targeting for vandalism"

This reverts commit eda1fd888ba7c1d6e6a835038353aadf3e43fecc.
vandalism is based on _reserved after all
fixed reapers
function name has changed...
