Auto generate the --task--all output

By auto-generating the content of the 'all' test suite from the content
specified in the task_states.md file for both the --task--applicable and
the --task--all switches, it ensures that the two test suite results
stays in sync, making it much easier to write new tests, or to alter
existing ones.
