Variable name and node path generation refactoring

[DarkMessiah]

• Variable names generation became more universal.
• Node path generation made by method 'path_to' instead of 'split'.

Hey! Thanks for the PR again. I like how you did the new node path.

But I don't agree with the variable name, I don't want it to be capitalized because it is not a const.

[DarkMessiah]

What does it mean not a const?

Edit: In godot 4 you can change node's name casing in settings. Here example of naming: https://github.com/godotengine/godot/blob/master/editor/plugins/canvas_item_editor_plugin.cpp#L5477

https://docs.godotengine.org/en/stable/classes/class_string.html#class-string-method-capitalize

Edit 2: var name := node.name.capitalize().replace(" ", "_").to_lower() variable name doesn't become uppercased, here to_lower in the end. capitalized need only for splitting.

[SanderVanhove]

Oh ok, I see, didn't see the to_lower there, excuse me 😅 I was just looking at the code, will try it out as soon as I can and will get back after 😄
