Subscribe to milestones and series

[Andrea Corbellini]

I've just discovered a new project and now I would like to know when the first release will be done and when the first tarball will be available. Currently I have just two options:

1. subscribe to the project announcements with my feed reader;
2. look at the page periodically.

However if the project owner doesn't want to use announcements and/or if I don't want to use feeds, then I have only (2). I would like to get mail notifications about the creation of:

1. new series;
2. new milestones;
3. new releases;
4. new download files.

StructuralSubscriptions should support this, but they were never completed. This requires a model to add a registry column. The subscribe to this <project|series|milestone> view need to show the registry option. The creation/publication/release events need mail notification hooks.

This would be extremely helpful for packagers of projects hosted on Launchpad.
