Subject: Introduce StandardShortcutWatcher to watch for runtime changes

Currently an application needs to be restarted before it can see
any changes made to the standard shortcut configuration. To notify
about changes a new class is introduced that looks for those
changes using KConfigWatcher and also updates the global map.
