A user posting a comment is marked as interested only if not the owner
and not the submitter. If in that case, the user will be anyway notified
of the changes to those issues.
The interest status or watch list is now shown in the list of the issues
and can be changed by clicking on the star in front of the title of an
issue when looking at an issue.
For each tab, at the exception of the project home and the
administration area, it possible to control the access rights if the
user is anonymous, signed in, member or owner.
