Comment support

Implementation of [#1546 (BitBucket)](https://bitbucket.org/zzzeek/sqlalchemy/issues/1546).

Very unfinished but I have reflection and setting after table creation working for PostgreSQL.

If you're not opposed, perhaps best to continue discussion on Gerrit?

Ensure CTE internals are handled during clone

2016-06-10T21:24:36+00:00

The CTE construct was missing a _copy_internals() method
which would handle CTE-specific structures including _cte_alias,
_restates during a clone operation.

Add IS (NOT) DISTINCT FROM operators

2016-06-06T19:53:25+00:00

None / True / False render as literals.
For SQLite, "IS" is used as SQLite lacks
"IS DISTINCT FROM" but its "IS" operator acts
this way for NULL.

Skip UniqueConstraint marked by unique=True in tometadata

2016-06-02T17:54:07+00:00

Fixes an issue where a Column would be copied with unique=True
and at the same time the UniqueConstraint would also be copied,
leading to duplicate UniqueConstraints in the target table,
when tometadata() is used.   Imitates the same logic used
by index=True/Index to avoid duplicates.  For some reason
a fix was implemented for Index long ago but never for
UniqueConstraint.

Support "blank" schema when MetaData.schema is set

2016-05-18T15:43:38+00:00

Previously, it was impossible to have a Table that has
None for a schema name when the "schema" parameter on
MetaData was set.  A new symbol sqlalchemy.schema.BLANK_SCHEMA
is added which indicates that the schema name should unconditionally
be set to None.  In particular, this value must be passed within
cross-schema foreign key reflection, so that a Table which
is in the "default" schema can be represented properly.
