Add support for ALL and ANY constructs to the Query API

[Nicklas Nordborg]

This is needed for solving #1129.

It would allow create queries like the one below which finds all members of groups have a name starating with 'A'.

SELECT usr 
FROM UserData usr 
WHERE usr = ANY( 
   SELECT member 
   FROM GroupData grp 
   JOIN grp.members member 
   WHERE grp.name LIKE 'A%'
)

The same result is possible to archive with a pure join query, but that generates duplicate rows if a user is a member of two or more groups that match the critera.
