Try a fix for the ModelData errors

tweak!

aha!

tweak
added more debug prints too

Small fixes

err stomp hopefully

More models + tweaks
Minor optimisations
Add grass/dirt "materials" so that they can be easily impaled into
Add sharpdata mutators that change the direction of existing sharpdatas instead of creating a bunch of different generic sharp types
Add .maxDamage string variant; "mass"
Makes max damage dependant on ent's mass, used on wood splinters
Check ent:GetOwner() when figuring out inflictor
Change freezing sticking logic, now creates a weak weld with the world if part of a contraption, should stop vehicles from getting stuck.
(if left alone for a bit, this weld will eventually be cleaned up and the prop, frozen)

Add sharp models!
