Adding support for ddl deparsing  CREATE/ALTER/DROP USER MAPPING and

changes from Vignesh C for
CREATE/ALTER/DROP SERVER
CREATE/ALTER/DROP COLLATION


I had to change the object identity of the user mapping as part of the deparsing
to make the DROP command work on user mapping.

FROM: "<role> on server <servername>"
TO  : "for <role> server <servername>"
