A lot more Cult fixes (#15161)

* Some fixes

1: ERT members can no longer be given as an assassinate/sacrifice antag objective.
2. Cultists attempting to teleport to a deleted rune will no longer be teleported into nullspace.
3. Re-ordered the cult Blood Rites spell code because it was bugging me. (sorry qwerty)

* Cult stuff

1: Cultists can no longer be chosen as a sacrifice target
2: Rune drawing is limited to one at a time (No spamming on one tile)
3: Removed some unneccesary `/improper`s from area names, for the cult Summoning locations
4: Changed a couple of colours to use defines

* QDELETED()

* Eye colour fix

* Reorganisation, Objectives, and Gender

The majority of the changes here are just reordering the procs, but there's a few fixes too:

1. Roundstart cultists now get given the 'servecult' objective.
2. Deconverting someone now removes their 'servecult' objective, so they won't be notified about target changes.
3. Stopped summoned ghosts from experiencing a spontaneous gender change.

* Screwdriver fix

* Prayer bead stripping

* Some more construct fixes

1: Fixed *all* holy constructs getting the 'Summon soulstone' ability
2: Fixed Wraiths getting their blue light reset to red after jaunting
3: Added a 'holy' variable to constructs, and made the holyification its own proc.

* qdeleted

* Construct Converting

Apparently you can convert holy constructs. Who knew!

* Another two weeks

Moved all the construct icon states to their own file, and fixed Nar'Sie constructs not getting a glowing effect.

* Grab fix

Fixed upgrading a grab having the ability to potentially transport the victim across dimensions.

* Not actually a cult fix but eh

Fixes: Runtime in outfit.dm, 114: bad number
And updates the cult corpse from legion spawns

* Teleport spell effect

Fixed the teleport effect for the spell being attached to the wrong mob.

* Small cleanup

* Eye colour cloning fix

* Veil Shifter

Fixed:
Runtime in cult_items.dm,355: pick() from empty list
Veil shifters not retaining any grabs after teleporting.
