Per node naming

[PatalJunior]

Add per node naming, so that we can name the nodes properly inside blender, cause the default numbering isn't good enough.

per node name isn't easy to do in Blender i'm working on some other do provide naming dev branch have an experimental one that use vertex groups for the name. i will need more time and testing to find a better solution. one of them would be to use vertex groups as a prefix so it's easier to separate parts
