* Add metadata_force to method overwrite_mask_fields. This allows to set metadata by ID that is otherwise not assignable to a mask. Useful in certain cases like the special filename mask objkeys
* add optional parameter filename_objkey, filename_objkey_id for upload_file and update_file. Which sets the filename in the options tab (internally done via a predefined obj_key entry)
* Hotfix create_folder method; used wrong bitset (mb_all) resulted in indexserver trying to assign 'freie eingabe' mask to a folder which is not possible on some elo instances. We updated our elo testing server to be more strict on this so we prevent this issue in the future
* Added configurable caching for overwrite_mask_fields (caches get_all_masks_names and get_mask_detail) * Fix a bug that caused a severe performance issue during overwrite_mask_fields
