We like spam from our build tool.

We like getting a nice email telling us that everything is OK.

Hudson should have an options to send emails:
1. To a specific list of people for failing builds.
2. To a different list of people for unstable builds.
3. To a third list of people for each stable normal build.

Or else add multiple email addresses sets and have tick boxes for each set
specifying the address email preferences from:
1. Every broken build
2. First broken build since normal or unstable
3. Every unstable build
4. First unstable build since broken or normal
5. Every normal build
6. First normal build since broken or unstable
