Dirk Mueller aa5cf3b673 - update to 1.7.7: ...

* Fixed issue where using :meth:`.Operations.create_table` in conjunction
    with a :class:`.CheckConstraint` that referred to table-bound
    :class:`.Column` objects rather than string expressions would be added to
    the parent table potentially multiple times, resulting in an incorrect DDL
    sequence. Pull request courtesy Nicolas CANIART.
  * The ``logging.fileConfig()`` line in ``env.py`` templates, which is used
    to setup Python logging for the migration run, is now conditional on
    :attr:`.Config.config_file_name` not being ``None``.  Otherwise, the line
    is skipped as there is no default logging configuration present.
  * Fixed bug where an :meth:`.Operations.alter_column` operation would change
    a "NOT NULL" column to "NULL" by emitting an ALTER COLUMN statement that
    did not specify "NOT NULL". (In the absence of "NOT NULL" T-SQL was
    implicitly assuming "NULL"). An :meth:`.Operations.alter_column` operation
    that specifies :paramref:`.Operations.alter_column.type` should also
    specify include either :paramref:`.Operations.alter_column.nullable` or
    :paramref:`.Operations.alter_column.existing_nullable` to inform Alembic as
    to whether the emitted DDL should include "NULL" or "NOT NULL"; a warning
    is now emitted if this is missing under this scenario.
