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).

- no longer transmutes artifacts;
- now creates ammo matching bow/sling's material level;
- allows an object to be reautopickuped;
- drops an object if things go awry somehow.

Effective stats fix

Hm, turns out exactly one place WAS using the weird form of outformat I replaced. Well, shed no tears for the dead, as the new version now compares effective stats more accurately-ish!
