Missing dependency to modemmanager

[Michal]

KDE network management plasmoid has enable/disable checkbox for activation of mobile broadband disabled when "modemmanager" package is not installed.
This package is however not part of the KDE networking dependencies thus for users not aware of this dependency it is unclear that without this package the mobile broadband is unavailable.
