Fix use after free bug

See merge request KartKrew/Kart-Public!315

Fixes an issue where mobjs with shadows would never get freed,

See merge request KartKrew/Kart-Public!314

due to their reference count getting reset after
having their shadows spawned, resulting in a reference count of -1
and the mobj never being freed, or a use-after-free during the shadow's thinker.
Also adds some P_SetTargets to P_BlockThingsIterator to fix an inconsistency I noticed while investigating this.

Move globalweather to before P_SpawnSpecials so that specials can properly change weather and have it communicated in savegames

It's designed to be referenced from P_RunTHinkers, whjich we aren't doing

with precipitation mobjs on netgame load
