Delete Edges With Item

[SoundsSerious]

SQLAlchemy has an option to delete relations when you delete an item, that would be a cool feature to have

Currently delete works like this for me:

db.query(Student).filter("LIKE(rec.name, 'test%')", prepend_rec_name=False).delete()

I think a non breaking change would be something like:

db.query(Student).filter("LIKE(rec.name, 'test%')", prepend_rec_name=False).delete(purge_edges=True)
