bi-directional many-to-many relationships, where
two objects made to mutually reference each other
in one flush would fail to insert a row for both
sides. Regression from 0.5. [ticket:1824]
with convert_unicode=True no longer embeds the actual
value passed. This so that the Python warning
registry does not continue to grow in size, the warning
is emitted once as per the warning filter settings,
and large string values don't pollute the output.

- fixed "toplevel" regexp to include tokens of the form foo-bar-toplevel (i.e. multiple dashes)
- some CSS adjustment so that all API headings are in gray.
after a dispose() occurs.
- Engine gains an "execution_options" argument and
update_execution_options() method, which will apply to
all connections generated by this engine.
- Added more aggressive caching to the mapper's usage of
UPDATE, INSERT, and DELETE expressions. Assuming the
statement has no per-object SQL expressions attached,
the expression objects are cached by the mapper after
the first create, and their compiled form is stored
persistently in a cache dictionary for the duration of
the related Engine.
- change #3 required change #1 so that we could test
a set of mappers operating over the course of many engines without
memory usage increase.
constraint gets moved to column level due to SQLite
AUTOINCREMENT keyword being rendered. [ticket:1812]
- remove some extra space in between constraint DDL
- added alias() to binary comparison test, fixing pg + mysql failures
including that use_ansi is set to False automatically,
NVARCHAR2 and NCLOB are not rendered for Unicode,
"native unicode" check doesn't fail, cx_oracle
"native unicode" mode is disabled, VARCHAR() is emitted
with bytes count instead of char count. [ticket:1808]
when limit/offset is used, i.e. the ROWNUM subquery.
However, Oracle can't really handle FOR UPDATE with ORDER BY
or with subqueries, so its still not very usable, but at
least SQLA gets the SQL past the Oracle parser.
[ticket:1815]
self.__class__ to determine the class of object to be returned
instead of hardcoding to ColumnClause/Column, making it slightly
easier to produce specific subclasses of these which work in
alias/subquery situations.
its connect string in normal Python 2.x mode - so we coerce
to str() directly. non-ascii characters aren't supported
in connect strings here since we don't know what encoding
we could use. [ticket:1670]
