- renamed file_operation_delete and to shfileops_delete 

- renamed file_operation_checkFlags to shfileops_check_flags
- added helper function shfileops_do_operation()
- added helper function shfileops_get_parent_attr()
- added helper function shfileops_get_parent_attr2()
- various cleanups in SHFileOperationW using these functions
