fix large unit placement error in atlantis
add bigwall type 9

probably needs some more adjustment, but this takes care of the pathfinding
at minimum
some adjustments to MCDPatches

stopLOS values and footstep sounds, sound -1 for "ignore and use floor"
only do bigwall checking if checking objects
no cap on alien bases

guess i misinterpreted something a while back.
fix the base defense score in info view
un hard-code sprite armor selections
insert another draw routine

draw routine 15 now applies to aquatoids, the old 15+ got bumped up one
update to Shoes !
merge + fix ....
