Function to get a list of class methods that are decorated with @validates.

[Former user]

In the attached patch file there is a new mapper method: 'iterate_validators'.

This function give to the user the capability to create a list of mapped class methods that are decorated with @validates.

I added a test in test_mapper.py

we actually had a dictionary of attr name->function already, so I put an immutable interface and kept your excellent unit test, a45da117889edba7ec0906d3af3fff7d83e5373a, thanks !
