Settle proper activation of the external UI interfaces (#1098)

Browse source 
This change was caused by investigation of UI event loop dispatch;
since the GTK UI is designed to run single threaded, any invocation
from other threads need to be diepatched explicitly.

A possible way to achieve this is to use Glib::Dispatcher, which
in turn requires that the current thread (which is in this case the UI thread)
already holds a Glib::MainContext

This prompted me to create a tight link between the external facade interfaces
of the UI and the event loop itself. What remains to be settled is how
to hand over arguments to the action in the main loop

It is of no further relevance beyond management of subsystem lifecycle -- which in itself is treated in Lumiera as a mere implementation concern and is not accessible by general application logic. Thus, the UI is largely independent and will be actively accessing the other parts of the application, while these in turn need to go through the public UI façades, esp. the GuiNotificationFacade for any active access to the UI and presentation layer.</pre>

<pre>LayerSeparationInterface provided by the GUI.
Access point for the lower layers to push information and state changes (asynchronously) to the GUI. Most operations within Lumiera are in fact initiated by the user through the GUI. In the course of such actions, the GUI uses the services of the lower layer and typically receives an immediate synchronous response to indicate the change was noted. Yet often, these operations may cause additional changes to happen asynchronously from the GUI's perspective. For example, an edit operation might trigger a re-build of the low-level model, which then detects an error. Any such consequences and notifications can be &quot;cast&quot; up into the UI, using this service here.
Beyond that, a call to trigger shutdown of the UI layer is also exposed here.
!Lifecycle and Threading concerns
The GuiNotificationFacade is installed as part of building the UI-Bus, which happens while establishing the GuiTopLevel. Yet there is a specific twist, insofar GTK is ''not threadsafe by design''. Any event handling and presentation changes will happen from within a dedicated UI event loop, which need to be explicitly started, after all of the primary windows and widgets are created and wired. Only after this point the UI becomes //life.//
A dedicated ''activation state'' is necessary for this reason -- which within the implementation translate into a queuing and dispatching facility to reschedule any calls into the UI event thread ''asynchronously''.
!Addressing of UI elements
Most calls in this interface require to specify a receiver or target, in the form of an element ID. It is assumed the caller effectively just knows these IDs, typically because the same IDs are also used as element IDs for the corresponding session entities. And, to start with, the whole UI representation of the session was at some point generated by //population diff messages,// which used the same IDs to indicate the creation of the corresponding UI representation elements.
