constraints should consistently add, or not add, themselves to Table

[Mike Bayer]

UniqueConstraint and PrimaryKeyConstraint both have auto-add, but ForeignKeyConstraint and CheckConstraint do not. I considered making it consistent by having none of them auto add (except Index), but seeing as I probably use UniqueConstraint in this way already and im sure lots of other people do, we can generalize the other way.

CheckConstraint and ForeignKeyConstraint also have a "table" argument for this purpose, this is again a little inconsistent but we should probably leave that argument in place.
