Lazily allocate sheet builder in ModelRenderer.

Browse Source 
Avoid allocating the sheet builder each frame until it is needed. For mods that do not need to render models, this avoids allocating a large buffer and backing sheet as it will never render to the sheet. For mods that do render models, but don't need any this frame, this avoids allocating a new SheetBuilder that will not be used.
