* Instead of duplicating what language tasks should be included in each
task.list.* file, let update_tasks add them dynamically at runtime from a
single list of languages supported by tasksel and D-I. This also makes
maintaining the lists a lot less painful.
* Indicate which tasks are "secondary" by adding a "-" suffix in task.list.*
files instead of hardcoding it in update_tasks.
