Prevent double notifications if redmine mention sent.

Hi,

Thanks for such a great plugin. I'd like to contribute my solution to #28

Any feedback is welcome :)

Thank you for the contribution! However, this goes against the redmine notifications settings as users who are expecting to receive notifications will all of a sudden realize that they are not receiving notifications.

Correct patch would be to add configurations related to email notification settings under user to allow for options like "Only for events when no one is mentioned", etc. See screenshot for the notification settings:

@hishammalik thanks for your feedback. I'm kind of new to Ruby and I'm not really getting to fix this as suggested.

I've found that the options are defined in User::MAIL_NOTIFICATION_OPTIONS constant; but I haven't found how to override that constant in a patch. I'd be happy to update the PR if you can point me to how to override the constant in a patch.
