DATABASE UPDATE: updated migrations, database tables file_manager_files and file_manager_alias is altered
Deleted now useless test file
Added alias_file_name to controller and view, converted raw sql query to model implementing db->join as instructed by bonfire guide
Began work with sorting output to file manager alias widget, where aliases to same file_id, file_name(or alias_file_name) target_table and target_table_row_id will be merged on the same row separated by commas between the different target_table_row_ids
