Activity-Lang: consider logic for dependency notification

Browse source 
...turns out there is still a lot of leeway in the possible implementation,
and seemingly it is too early to decide which case to consider the default.
Thus I'll proceed with the drafted preliminary solution...

- on primary-chain, an inhibited Gate dispatches itself into future for re-check
- on Notification, activation happens if and only if this very notification opens the Gate
- provide a specifically wired requireDirectActivation() to allow enforcing a minimal start time

In a similar vein, also ''notifications'' need to happen decoupled from the activity chain from which they originate; thus the Post-mechanism is also used for dispatching notifications.
