Merge some Bootil changes from x86-64
Remove mp_usehwmmodels convar (unused)
AvatarImage panel changes + defer material cleanup till render end
AvatarImage keeps track of textures it creates and reuses them, preventing exhaustion of texture name symbol list
Deferring material cleanups a little makes it more likely the materials and textures are no longer used by any part of the renderer, allowing refcounts to reach 0 naturally.
Added GM:OnClientLuaError( strErr, ply )
Remove stray space indentation in some Lua files from PRs
Updated FGD files
Added inputs to light_environment, removed point_clientcommand and point_servercommand since they do not work in Garry's Mod.
