Secret door cheese

[benlp91]

if you place 2 secret doors next to each other, you've created the ultimate cheese bonus. why ? even if they spot the first one, they do not spot the second one and think there's no way to go. and because of the reason creatures do not properly attack doors and traps this is a very easy way to cheese and it shouldn't be like that. Better would be if the creature attacks the secret door if it has it spottet.

i forgot to tell: vanilla traps are not destroyable so there's no problem to change it overall, but vanilla doors are and we might not want to have imps to be attracted to fight against doors, so this might need a configuration line just for the secret door

Or just exclude spectators and diggers. Related issue: #3666.
