Better stealth

If AI gains LoS for the first time but fails to spot you, they treat itas if they haven't seen you for 10 turns, instead of as if they had spotted you that turn.

Shield of Light fix

Shield of Light loves to proc unarmed attacks (becuase it uses weapon.special_combat, which is always nil because weapon already IS a combat table!). So I fixed it and made it deactivate without a shield, too.
Special thanks to StarKeep for alerting to this.

Callback fix

I honestly wasn't expecting THAT.
Due to an old typo in learnTalent, callbacks for passives were added once per talent level. So I fixed that, twice, just in case.
(Grumble grumble wouldn't have happened if __sorted updated at once)

tiles can flip on x/y; used to make an x flip when creatures move left or right. assumes all are drawn left faced, which is not the case and needs fixing

No no martyr

No auto use low cd

Wouldn't say it's pretty but it works.

You better run

(I hope my K-Pop reference is appreciated) Doctornull was crying a lot lately about enemies potentially doing a lot of damage on you at once at the autoexplore breaking point due to either "not notice stuff at the end of your turn" thing or projectiles. This makes rest/run a bit more paranoid when it comes to enemies.

Small fixes

A couple o' typos I've ran across.
