a few QOL changes re base cooldown

the friendly challenge is excellent, thanks for it!

it would be nice minor tweak if a few things didn't set off the cooldown on bases though:
primarily, if just rearranging newly upgraded wall segments, without changing the location of walls overall
secondarily, adding a new building, and then not moving it

and lastly, though it's been asked for before, a lock active base feature is even more important now, to prevent accidentally setting off the cooldown with an errant touch
