fix drop dialog and some others

Manaburn, baby

Ask and ye have received this highly complex and carefully-crafted change.
(Honestly, we need more cleanups like that. We need to be able to make small libraries to import from whenver and use in talents/egos/etc. Is it doable?)

Infinite lua chain

We all know how an NPC selecting an erroneous talent again and again wrecks the game by infinite Lua chain. This commit fixes it!

potential recoveries.

Summon AI fix

A bug which became much more prominent with introduction of temporal clones (which have high chance to have access to less-than-a-turn talents) and Temporal Fugue in particular (where turns not ticking down AT ALL when AI is far from player becomes a serious concern.)

This commit makes for a more predictable and accurate summon_time behaviour, making it tick down in NPC.actBase if ai is "summoned" and the creature isn't out of timeflow.

IMPORTANT: considerations need to be made for Mucus Oozes (which have 70% global speed) and Bloated Oozes (50%), as it effectively brings their summon time to what's advertised (6-10 turns.) Whether this is desirable needs to be decided.

"Shrug off" fix

(Seriously, no one noticed it before? O_O)
This fixes shrugoffs to work for a player and not just write a message in chat.
So I was testing my addon, and witnessed shrrugs off happen but not happen. I added lots of debug output, but the return value of Actor.on_set_temporary_effect seemed to just disappear. Then I remembered something might've overloaded it.... and there I am!
(It worked when shrugs off still worked by setting dur to 0, I imagine. It also worked for NPCs.)

Arcane Power fix

Arcane power spellpower bonus was applied before calculating its resist bonus, which resulted in more-than-advertised resist and different resists advertised with it on and off. This branch aptly fixes both problems.

Absolute tiles

Made it possible for Entity to use absolute dta paths in image=, and for talents and effects as well.
Also support for addon+path syntax, didn't know which would be more desirable.

New lore for the ogres
New zone to unlock the ogres

moar work on ogres unlock, nearly done

damDesc fix

Well, having a global function be redefined at an arbitrary point in our lives is not the greatest thing ever.

oh and many WIP ogre stuff
