Subject: launcher: add favorite apps (#946)

* launcher: add favorite apps

Favorite apps always appear above non-favorite apps
Accepts regex, same logic as #920
Added the same regex logic to hidden apps
Added util file may need to be relocated

* addressed requested changes

* fix: Renamed newly added util singleton

Also added a null check to favorite icon loader in AppItem.qml

* controlCenter/launcherPane: added favorite apps

added icons to the app list to indicate if they are favorited/hidden
marking as favorite/hidden is desabled if the other is selected

* favouriteApps: renamed from favorite to favourite

Also disabled favorite/hidden switch for entries added as regex

* appDb: added notify and emit to favoriteApps

* controlCentre/Launcher: Fixed bug with favourite switch not enabling itself when no hiddenApps exist

Added a comment to explain the enabled state of the switches
icon loader is now a single loader rather than two, hidden icon has
priority

* spelling mistakes

* fixed warning

* formatting fixes
