Send email to particular users when status changes
I think this request is similar to #6220.
When the status of an issue changes it would be nice if some people could be explicitely informed about this. For example, if an issue is set to resolved an email should be sent to QA so that they know that they can start testing. QA may then set the the status back to assigned (or reopened or whatever) so that the developers get an email about that the test was not successful. Or QA sets the status to verified so that the project manager knows this task is completed.
I could imagine that you add a row to the workflows: the roles that should be notified if an issue status changes to a certain state. I think it doesn't matter which status the issue had before. However, the email should look a bit different so that the recipient immediately sees that he or she has something to do now.
