Tremcar 3A Sanitary v1.2 1.35.x

Changes 1.2
- 1.35 model format
- New custom cargoes (canola oil, hfcs, maple syrup, peanut oil)
- DOT tape now uses retroreflective effect

This is a thorough rework of Corby's Tremcar food grade tanker with a drastically lower poly count, tweaked proportions, and some texture/material work that I'm fairly happy with. It uses the base game milk cargo, supports advanced coupling and has animated landing gear — all that good stuff.
