Added feature "action on typing", i.e. cosmic-workspaces opens cosmic-launcher or cosmic-app-library, if the setting is set.

When opened by typing, cosmic-launcher or cosmic-app-library are closed when existing the workspaces overview.
Changed exiting workspaces overview by pressing Escape from KeyReleased to KeyPressed to improve interaction between cosmic-workspaces and cosmic-launcher/cosmic-app-library.
