Add App list menu to Tray UI

- Modify Window.qml and Systray to show the App menu upon clicking the App button
  on the top-right. Fall back to opening the general URL in case no apps are found.

- Introduce a new UserAppsModel in UserModel.cpp to access the fetched server Apps
  from AccountState (propagated down from the User class).
