Paint gun consolidation and crate/locker painting (#21902)

We don't need a million paint guns. Makes it so a single paint gun can
paint whatever you want. Which now also includes crates and lockers.

changes:
- rscadd: "Paint sprayers can now be used on unpainted crates and
lockers to give them a custom appearance."
  - rscadd: "Adds paint sprayers to Hangar Tech lockers."
- qol: "Moves pipe painter functionality to paint sprayers; pipe
painters now just flavor objects on some offsites."
- qol: "Adds paint sprayers to allowed items list for utility
toolbelts."
- imageadd: "Codersprites pipe painter with recolorable paint storage
component indicating current color (used by paint sprayer)."
  - imagedel: "Removes old paint sprayer sprite."
- bugfix: "Removes old runtime caused by targeting turfs w/ paint
sprayers that don't have flooring singletons assigned."
