Egos here we go

Oh yes, those juicy rerolls by opening a levelup dialog. Well, no more. Hopefully.

Small fixes

I'm not bothering repeating commit messages!

Cursed aura

* No more artifact transposition when cursed sentry dies.
* Ammo matches the archery weapon in quality now.
* Remembers your choice of weapon after the first time, you can alter the choice with a helper talent. (Yes, that IS old Command Staff icon. It's not used anymore!) Actually not annoying to use mid-combat!
* Levels up its stats to be more damaging.

Small fixes

Just a bit more error handling. Errors get masked after a dialog, as I've discovered.

More fixes

more fixes and balance stuff

I just can't get it right, can I. *sigh* At least now it should work, and I also fixed a couple of typos.

(esp now that splitLines is kinda irrelevant since we use font:draw)

Fixed textzones being too spacious/cut off sometimes as a consequence (when they have many tall letters).

Ice Storm stays in place after the source is dead (just in case); map effects actually check for duration set to 0

Backup guardians consistently increase material level on all zones (hello never-dropping Crystal Heart).
