Fix sessionmaker.__repr__

A comma separating 'class_' from the other args. It's still there even when kw is empty, which is syntactically correct.
Remove reference to defunct class

We should probably reword this entirely as, IMHO, this should be in the
changelog and not in the doc proper (which should only describe the
current state of affairs).

Added support for new :attr:`.Session.info` attribute to
:class:`.scoped_session`.
- The ``viewonly`` flag on :func:`.relationship` will now prevent
attribute history from being written on behalf of the target attribute.
This has the effect of the object not being written to the
Session.dirty list if it is mutated.  Previously, the object would
be present in Session.dirty, but no change would take place on behalf
of the modified attribute during flush.   The attribute still emits
events such as backref events and user-defined events and will still
receive mutations from backrefs. [ticket:2833]
- The :class:`.RowProxy` object is now sortable in Python as a regular
tuple is; this is accomplished via ensuring tuple() conversion on
both sides within the ``__eq__()`` method as well as
the addition of a ``__lt__()`` method. [ticket:2848]
break up behavioral changes into ORM and Core
- Fixed a regression caused by :ticket:`2812` where the repr() for
table and column names would fail if the name contained non-ascii
characters. [ticket:2868]
- Fixed bug which prevented the ``serializer`` extension from working
correctly with table or column names that contain non-ASCII
characters. [ticket:2869]
adjustment to work on py3k as well
fix [ticket:2868] some more
something changed the name here, probably one of those doc pullreqs
- cleanup
