Provides compatibility loading older files outside the context of a library. Older material files were loaded by specifying a path. The new material system used the path to associated the material with a library, which may not be appropriate for legacy files. This change allows the use of materials outside of a library. Additionally, legacy files often have name/value pairs not part of the standard list of properties. Since these were unable to be mapped to a model property they were ignored. Materials now maintain a legacy map to hold properties not associated with a property model. These properties are considered transient and will not be saved. It is not intended for this feature to be used as a generic container for properties not mapped to an appropriate model. Fixes FreeCAD#13302
