Email report on update

[mfernau]

I can't find a way to configure this plugin to send an email notification if an update occurs. For me it would be handy to get a notification if one of my developers just checked in a new commit to one of his assigned bugs. Either by directly sending a mail or alternatively by adding a new note (like it is already possible by resolving an issue) which would then fire a new notification mail.
