Shortcut add-on: change to accomodate tracker add-ons

* Ignore shortcuts regardings tracker add-ons. Its settings file is now shared
with Tracker, and those are now handled by Tracker.
* Use a BPathMonitor as specified in a TODO to check the presence and changes on
the settings file. (#6278)
* Use a message to ask Tracker to launch/open folders as specified in TODO
