[ZODB-Dev] Ordering before commit hooks

Hi,

I would like to order the before commit hooks on a transaction by being
able to specify an order for a subscriber at registration time. For the
moment, they are called in the order they've been registred.

The order argument could be an integer with a default value to 0 added
to the registration method.

We could just insert the subscriber wihin the queue according to this
order parameter if found *or* sorting the queue according to this
parameter before flushing the queue and calling the hooks.

What do you think ?

	J.
