AccountManagerPlugin not working on trac 1.4 (due to changes in trac.notification)

[borja@…]

How to reproduce:

1. install trac 1.4
2. set log level to DEBUG in trac.ini
3. install the AccountManagerPlugin plugin, set it up as suggested in the plugin docs
4. start trac

Then, if you look into your trac.log file, you will see something like:

Accesing trac using a browser shows no login link, /login gives a not found page.

Digging a bit through the sources of both trac and the plugin, the NotifyEmail class was marked as deprecated some time around release 1.2 and it was removed before 1.4.

So, I guess the plugin code needs updating to use the new API.
