Fixes to example manifest storage and use. Save event type and comment with them. Explicitly add them to the event table, rebuild will not do that for us, with the missing references.
Sorted out the low-level method naming, naming in the action layer, and command specification. Updated help results to match. Back in low-level layer "seen", fixed pending-all, must not drop the table, just empty it, otherwise forall-pending will break.
Added tests for the control methods. Passing. Now we can start testing the next higher layers, i.e. manifest parsing, then mail generation, and receiver collection.
