Provide ability to favorite repositories and projects

It would be very helpful to have a way to favorite a project or repository, and to have a way to see all favorites in a single view. The current method of having "watched" repos display in the My Work view is cumbersome, especially for those of us who work primarily on a team.

It would be very nice to have a star icon in the blue navbar, just like the one in Jira.

There's a request for this to be implemented in Bitbucket Server already: https://jira.atlassian.com/browse/BSERV-11158
