Added L4D1 model variant. (Might create something new for said variant later?)

-Added HUD icons

This add-on has been completely redone from scratch. Changes include:
Resize & proportions; Weavile is no longer huge in comparison to other infected & the survivors.
HD Textures; I have switched texture formats to get the highest quality textures, & other add-ons of mine will be receiving the same treatment in time.
Custom, cartoony shaders, a consistent thing across my more recent add-ons.
New FPS arms.

-Fixed consistency errors when playing on servers with sv_consistency 1.
