A static function is added to EditorNode which allows for filename
disambiguation given a list of filenames and the corresponding list of
absolute paths for those files. This function is then used to
disambiguate scene and script tabs in the editor.
The existing theme editor icon could be unintentionally set for any
global class with matching name (`Group` icon, `Group` class_name etc),
which would only show up in the "Create Dialog" context, but not the
scene tree dock.
This change prevents this behavior, and ensures that the icon can be
actually overidden by explicit icon path in `class_name`, if there's any
custom icon to begin with.
The correct built-in type's icon is fetched for child classes if there
are no custom icons detected throughout base classes as well, so it
isn't left empty for those cases.
`get_global_class_name` for `GDScriptLanguage` is slow because
it forces to parse an entire script each time. This patch ensures
that the icon is actually fetched from the EditorData where they
are loaded beforehand.
This change also makes the behavior consistent with the existing
`get_object_icon` method in EditorNode.
ToolButton has no redeeming differences with Button;
it's just a Button with the Flat property enabled by default.
Removing it avoids some confusion when creating GUIs.
Existing ToolButtons will be converted to Buttons, but the Flat
property won't be enabled automatically.
