"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

Steamtech UI fix fix

Seems like I managed to break exactly one, not-so-often used dialog, namely "Load Premade", because resized dialogs cannot handle interdependent UI elements. Well, now they can, as good as possible without making overly complex linear equation solvers.

New Actor:addParticles3D to automatically handle particles with "noup"

Steamtech UI fix

More generally, "any UI that changes separator width fix and some fancy math". Levelup dialog now contains much less magic numbers and instead uses the full power of Setup UI. All other dialogs touched mostly involved really small fixes because they're p basic.
Seriously. It was a hassle. People, write flexible code.
