Item event framework (plus other changes now)

[Logg-y]

Related changes:

Modified existing item activate scripts to use it (else the framework would fire them during equip etc too)
Polymorph merge should work.
At the moment nothing live actually makes use of this. This commit contains is_physadapt as a simpleish demo of it, to use, set the tag of an item to "physadapt" and unequip/requip it.

Other things that are in this commit:

Fix towards identify webhook firing twice from stores
Fix compile warning from 70_mod_polymorph attempting to use a variable in its own initialisation statement
Minor treasure map dig code refactor. Also made the map UI close itself when completed (previously only finding treasure in undiggable locations would do this)
Fix for ILR text in item descriptions not updating when the item's actual ILR changed
Fix on hit cast properties on weapons getting merged onto creature hides during polymorph
Fix batch file stop scripts (swapped yaml names, and wrong directory)
Fix dev folder compile for new scripts
Fix one-off compile complaint messages
Add two new item properties that don't show ingame that can be used to manipulate item prices (and ILR).
Added an Isle of the Maker creature palette category as there are several constructs with the same names and life was getting confusing.

Actual content changes in this PR:

• Damage no longer removes invisibility.
• Fix adventurers in Neverwinter spawning at higher levels than intended.
• Isle of the Maker golem changes: Iron Golems were disproprotionately nasty compared to the other types.
  • Iron Golem: 17 HD -> 15 HD, 32 Str -> 28 Str, 30 AC -> 28 AC
  • Stone Golem: remains 14 HD, 25 Str- > 26 Str, 23 AC -> 26 AC
  • Clay Golem: 11 HD -> 13 HD, remains 24 Str, 21 AC -> 24 AC
  • Animated Artifact: 21 AC -> 23 AC, 13 Str -> 16 Str
  • Second level: Slightly increased the number of smaller golems in the early encounters, especially on Ferron's side. The numbers of golems in the boss fights are unchanged.
• Henchmen killed 3 times should no longer despawn instantly, letting you try to raise them if you want
• Isle of the Maker book text now mentions a way to destroy certain problematic golems
• Flail of Jergal: +1d4 negative vs diseased targets

Finally got round to sorting the conflicts on this - it is probably good to go, just pending possible server hardware migration.

Scratch that, this needs a treasure seed.
