Add mls support for some db classes

Mirror file/dir approach.

db objects which do not contain other objects at multiple levels are analogous
to files:
	db_sequence
	db_view
	db_procedure
	db_language
	db_tuple
	db_blob

db objects which are capable of holding objects at multiple levels are
analogous to dirs:
	db_database
	db_schema
	db_table
	db_column
