Require 'waving = 3' in a nodedef to apply the liquid waving shader (#8418)

Browse Source 
Makes the liquid waving shader per-nodedef like waving leaves/plants,
instead of being applied to all liquids.
Like the waving leaves/plants shaders, the liquid waving shader can
also be applied to meshes and nodeboxes.

Derived from a PR by t0ny2.
