configurable issue tracker default
It would be very handy to set the default tracker per project.
Furthermore it would be nice to assign a default tracker to a user group (per project).
Supposed you have a group of testers - they will usually create issues in the "Bug" tracker.
On the other hand reporters from the marketing departement will usually create issues in the "Task" tracker.
You want to avoid that either group creates an issue in the wrong tracker.
