World tint: tint map-static props through IStudioRender

Most of the crates are prop_static, which have no client entity, so writing
m_clrRender only reached the three dynamic ones. Hook the StudioRender
interface (VStudioRender025) on the interface object's vtable: substitute the
prop colour in SetColorModulation/SetAlphaModulation while
DrawModelStaticProp is drawing a models/props model, and set the modulation
explicitly before the original draw in case the engine sets it just before the
call.

Vtable indices verified by disassembling CStudioRenderContext: 27 = three
float stores from the argument pointer, 28 = one float, 30 = the
DrawModelInfo_t-drawing entry with three arguments (the 2013 SDK header lists
these slots five positions earlier in this build).
