Support for disabling notifications on issue tracker when the update is done via commit (BB-3567)

Bitbucket supports adding services to commits e.g. email, issue tracker update etc.

Generally developers get the commits via the email service. But I like the idea of also enabling the issue tracker service for the sole reason of be able to see all the code changes done for a particular issue at one place.

But when both the services (email & issues) is enabled, we end up getting duplicate emails for a single commit (one from email and other from issue tracker update).

It would be great if you guys can provide an option to disable issue tracker notifications if the update is done via the commit.

Please let me know if you need more info.

Thanks.
