- schema.copy() functions will copy dispatch, but only for those events

added with propagate=True.   needs tests
- oracle/fb test schema uses event w/ propagate=True to apply
Sequence to primary key columns with test_needs_autoincrement.
this does actually test the propagate=True flag a bit since it's
needed in the declarative mixin tests where the 'id' column
is copied.
