Feature request - signals in Flask-SQLAlchemy

Feature request - signals in Flask-SQLAlchemy

As we now have signals in Flask (through blinker) it would be a good
idea to be able to use these in Flask-SQLAlchemy. This could be done
through a mapper extension:


http://www.sqlalchemy.org/docs/reference/orm/interfaces.html#sqlalchemy.orm.interfaces.MapperExtension

Typical signals could be e.g after_delete, before_insert etc. fired by
the respective extension event.

This would have a number of uses, for example updating a denormalized
field, logging, sending an email, etc.

Sounds good. Will implement that. Can you file an issue so it does not get lost?
