Display a block that lists assigned issues for security team members

It is quite a journey to find out what issues are assigned to a member (you would need to go to '/project/issues/search' and search by username). By having a block (and a link to the page view) that lists issues that are assigned to a team member, they can easily review the issues' statuses. It would also make it easier for the coordinators to help the members resolve assigned issues.

The block should:

1. display issues that are assigned to the logged-in user:
- Based on $user->uid, the block displays all the assigned issues, as well as their statuses

2. displays, in each user profile page, issues that are assigned to the owner of the profile
- based on the uid in the path, it lists all issues that are assigned to that user
- access to this information should only be granted to the security team members (this could be controlled by 'view user profile' permission)
