EditorScenePostImportPlugin & EditorScenePostImport redundant?

[dpalais]

I believe it may be useful to change the signatures of EditorScenePostImportPlugin's _pre_process() and _post_process() to match that of EditorScenePostImport's _post_import(). That way EditorScenePostImportPlugin may too radically transform the imported scene and EditorScenePostImport may be removed.

I'm making a 3D game with modular and customizable characters and the way I mostly use EditorSceneImport currently is to look for a particular node, for example a Skeleton or an AnimationPlayer, and make it the root and only node of the imported scene. I would like to use EditorSceneImportPlugin to replace my workflow of setting an EditorScenePostImport script for every asset I import.

Using an alternative custom importer for assets that already have one is very cumbersome with the forced editor restart required and is redundant as well.

By the way a rename for EditorScenePostImportPlugin may be desirable. EditorSceneAdvancedImportPlugin perhaps?
