Be able to see all notification on the web

There's nowhere to see all notification on bitbucket.org!

The only way to get notification is via email (or integrated app like Slack/Hipchat). This is not useful, since our email will be floated with a lot of emails.

On Github, there's a notification center, where we see all the comments on issues/PR, which is very helpful to see what's updated.

I hope this is added to Bitbucket as well.
