traceback: allow providing a local support contact point

The extensions blaming code is fine for casual users but pretty terrible for
corporate environments that can deploy a large amount of extensions to
unsuspecting users. Reports will likely blame a random "innocent" extension (in
our case crecord) and the hint in the message will triggers endless debug
attempts from the user.

We introduce a "ui.supportcontact" option that allow such big company to redirect
their users to their own support desk. This disables all extensions blaming and
just point people to the local support in all cases.
