Can't set schema using declarative extension

I tried to redefine some of my classes and mappers using the declarative extension in 0.4.5, but I couldn't see how to set the schema argument on the table. At runtime, schema==None, which won't work for this application.

Looking at the code, it appears only "autoload" is honored, and other Table args are ignored.

Perhaps we could recognize a schema attribute on a declarative class?
