node_shader_utils: several fixes, improvements and cleanups.
Fix broken behavior in case of texcoords mapping (we do need texcoords node in all cases, then, even for UV coords...).
Use nodes by default when generating new write-allowed wrapper around a material.
Do not try to find nodes in existing tree all the time, do it only once, even for lazy-initialized nodes (through accessors).
Fix ugly spacing in property accessors (since it looks like some people do not like a single 'block' with both getters, setters and prop definition, at least use one sep line everywhere (and two sep lines to separate properties)...
