[bug] [operations] Fixed issue where using Operations.create_table() in conjunction with a CheckConstraint that referred to table-bound 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.

[bug] [environment] The logging.fileConfig() line in env.py templates, which is used to setup Python logging for the migration run, is now conditional on Config.config_file_name not being None. Otherwise, the line is skipped as there is no default logging configuration present.

[bug] [mssql] Fixed bug where an 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 Operations.alter_column() operation that specifies Operations.alter_column.type should also specify include either Operations.alter_column.nullable or 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.
