This involved a significant change in event handling for automation region views,
but it brings it into line with how it works for other things. On button press
we initiate a drag, then if no motion occurs, the Drag returns false during
finalization, and only then do we continue through Editor::button_release_handler()
to eventually end up in ::add_automation_event().
Although it is a substantial change, the fact that it now works the same
way for audio regions, automation regions and automation tracks seems
like a definite plus.
This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
In case of MIDI CC/Bend/Pressure etc events, the underlying
data is provided by a MidiTrack (is-a Automatable) and not
an automation-control.
When directly calling AutomationControl::set_automation_state,
the AC disables automation-watch using shared_from_this().
With the Evoral::Control used for MidiTrack event-lists this
results in a tr1::bad_weak_ptr.
This is in preparation to always show a line, which show
the current value in case there are no automation points yet.
It also unconditionally snapshots the current value without
changing automation modes to touch/write first.
Extra XML/GUI has not been in use since ages.
Automation Lane visibility is saved as GUIObjectState.
This properly marks DropDown Menu items as active when a
Plugin Automation Lane is displayed
When a plugin is deleted, automation-lanes of the given plugin
are removed, but previously a pointed to the deleted lane remained
in the selection.
This caused crashes later when the track selection is used. e.g.
during sensitize_the_right_region_actions()
Note that ~TimeAxisView() also emits CatchDeletion (this);
however "this" fails to be dynamic_cast<AutomationTimeAxisView*>
because that d'tor has already been completed.
