Saving drawing shading styles to ifc #2991

Now shading styles are stored in ifc. It's actually stored in json file (by default it's in projects "assets/shading_styles.json") and the path to it saved in `EPset_Drawing.ShadingStyles`. Current shading styles is stored in `EPset_Drawing.CurrentShadingStyle`. This change could potentially cause problems but I've added some temporary fallback to make sure `EPset_Drawing.ShadingStyles` will be set to some default path and default shading styles will be copied to the project's folder.
