schematypes should get copied during a column.copy()

[Mike Bayer]

consider the case of a table with an enum:

t = Table('t', m, Column('data', Enum([2, 3](1,), name='myenum')))


t2 = t.tometadata(othermetadata, schema='someschema')

[Mike Bayer]

this needs to be an explicit feature which we'll name "inherit_schema". Otherwise there's no way to have the schema type with a schema name independent of that of the table.
