AI Node graph fix. (Why does this matter anymore.) I may have to potentially do a follow-up with the addition of CS:S assets to GMod. Doubt anyone would care though, just want to ensure good compatibility next update.

Models packed and light fixes. Final update.

Updated the sign and building proportions. Tons of detail was added too like decals.

Better fire extinguisher and HDR lighting darkness has been fixed.

Better AI nodes, new storage room, and other fun details.

Map name changed from "gm_foodland" to "gm_foodland_2021." This is to make room for the other map submission and avoid conflicting files.

Added skybox, decals, soundscape, and cubemaps for both LDR and HDR.

Cubemaps.

Added a NAV file for Nextbot navigation system.

Added cooler displays, made bathroom stall doors breakable, and made the checkout counter look better.
