[WB] Changing WF/Task/Action name is not reflected in YAML

[Timur Sufiev]

While changing these entities' names causes the appropriate title change in left-side form, it's not reflected in right-side YAML. Most obviously, the event is not propagated to customized .toYAML() method

    Fix changing Action/Workflow/Task id

    To make it happen <collapsible-group> directive had to undergo the
    same transformation that was applied to <panel> directive: instead of
    passing just a '@title' reference, the whole '=content' reference is
    now passed to the <collapsible-group>'s scope. This allows to use
    <editable> directive inside it with 'ng-model=group.title' as
    getter/setter method. Yet <collapsible-group>'s scope wasn't remade as
    radically as <panel>'s was - '&on-add' and '&on-remove' are still
    there and left for future refactoring.
