add __table_args__ to declarative

[Mike Bayer]

Not sure about format here, my immediate reaction is:

__table_args__ = (DDL(), DDL(), {'mysql_engine':'InnoDB'})

# or

__table_args__ = {'mysql_engine':'InnoDB'}

theres the possibility of adding __table_kwargs__ as well but I feel like this is too much.

+1 This came up on the IRC channel yesterday. I think the syntax works fine.
