Added pre-rendered spawn icons

DEFINITIVE FINAL EDITION UPDATE

Redone materials and textures to resemble the original game as closely as possible
- Detail texture is now rendered over cubemapping (and certain other transparent effects due to bad alpha sorting, can't fix this, sorry)
- Visor now has a subtle fresnel effect
- Armor colors taken directly from the game

Redone view model hands
- More proper model with less jank looking fingers and rigging
- Rubber suit material's cubemapping is now properly colored and has a subtle fresnel effect

Redone player model hitboxes
- Hitboxes are now an exact fit for each body part for more accurate and realistic hit detection
- Applied hitbox type values to the corresponding hitboxes so that they properly calculate damage per body part

Addon now uses and requires the 'Env_Lightmap' material proxy addon to prevent the model from glowing in the dark due it's use of static cubemaps

Corrected visor and armor cubemap directons (were previously mirrored)
Gave first person arms a new and correct cubemap for the rubber/not armored parts
Slight tweak to the cubemap tint color for Master Chief's armor

Reflection masks were a bit darker than they were supposed to be

Updated visuals to more closely resemble the original Xbox version where the armor detail texture is visible through the reflectiveness, thus making it appear more gritty and detailed

Made armor reflection tinted by the armor color for a more 'game accurate' look
Fixed detail texture making the armor overly bright

Minor shading tweak - Removed $halflambert

None Provided

Fixed ragdoll weight being floaty

Removed 'env_cubemap' skin because some maps (and parts of maps) would leave the player model without a reflection
Models now only use Halo's cubemaps
Added detail texture to the player models and view models
Minor tweaks to the player models, textures, and materials
Player model ragdolls now have a proper physics model
