Core: Replace ICoreListener by std::functions

ICoreListener::coreAboutToClose() remains in the core,
ICoreListener::editorAboutToClose() is handled by a new
EditorManager::addCloseEditorListener() function.

This removes the need for some boiler plate code resulting
from the need to implement the interface in custom classes
(DesignModeCoreListener, EditorClosingCoreListener,
PojectEplorer::CoreListener and VcsBase::CoreListener).

EditorManager::addCloseEditorListener

+    to veto on closing the application.
+
+    When the application window requests a close, all listeners are called.
+    If one if these calls returns \c false, the process is aborted and the
+    event is ignored. If all calls return \c true, \c ICore::coreAboutToClose()
+    is emitted and the event is accepted or performed..
