Update to ZDoom r 2145:

- fixed: Rocket trail particle positioning only worked when the rocket was moving.
- fixed: Sector_SetWind and Sector_SetCurrent were not usable in scripts called from a line.
- added Gez's A_Mushroom extension.
- added a minimum threshold for damage thrust to avoid micro-velocities being set for actors.
- fixed: Strife's Oracle is not a living thing and needs the NOBLOOD flag.
- fixed: Chex Quest's finale pic was wrong.
- fixed: Being resurrected by an Arch Vile did not restore flags5 and flags6 to the defaults.
