Add && array criteria method

[jwoertink]

I don't know what this is called, but it's handy

SELECT * FROM users WHERE tags && '{ruby,crystal}'::text[];

This returns all users that have either ruby or crystal in their tags array, but not necessarily both.

It would be like

UserQuery.new.tags.has_any(["ruby", "crystal"])
