While visits of ally heroes supposedly occur accidentally It's still nice to handle it's gracefully.
No reason to prevent visits completely as they useful if hero have skill like Scholar.
This make my new shipyard-related changes work properly and might improve owned dwelling usage.
In case there still some code that might cause useless visits it's better just rewrite it insted of removing objects from visitableObjs.
This one fix issue 2455. We still need to do something with ArtifactID::ART_LOCK or ids for artifact from mods since they might conflict with each other.
Now AI only check full object list if there is no suitable objects found in current sector and sectors around it.
This optimization drastically increase wandering performance on maps with tons of objects when AI see most of it.
That wouldn't be as big issue if problem affected few files, but it everywhere in codebase.
Fixed it everywhere since in most files that is the only code with wrong indentation.
CQuest::checkQuest cant be used for border guard since CGKeys not yet work using quests.
Currently border guard have MISSION_NONE quest that always return true and make AI stuck.
