- Fixed bug in 0.9's foreign key setup system, such that
the logic used to link a :class:`.ForeignKey` to its parent could fail
when the foreign key used "link_to_name=True" in conjunction with
a target :class:`.Table` that would not receive its parent column until
later, such as within a reflection + "useexisting" scenario,
if the target column in fact had a key value different from its name,
as would occur in reflection if column reflect events were used to
alter the .key of reflected :class:`.Column` objects so that the
link_to_name becomes significant.  Also repaired support for column
type via FK transmission in a similar way when target columns had a
different key and were referenced using link_to_name.
