cant use non-hashable mapper args with declarative

[Mike Bayer]

really surprising nobody has reported this. the "column_copies.get(v,v)" line means you can't use exclude_properties, include_properties, anything else list based (well you could pass a tuple). the check there should test for hashable first before doing that check. wacky

[Mike Bayer]

class MyClass(Base):
    __tablename__ = 'foo'
    type = Column(...)
    # ...

    __mapper_args__ = {'exclude_properties':['b']('a',), 'polymorphic_on':type}

probably limit the test to "polymorphic_on", "version_id_col" for now, + tests in test/ext/test_declarative.py

Added check to limit column set to only 'version_id_col', 'polymorphic_on'
