BlackBerry QNetworkConfiguration: Keep track of bearer type

I.e. let the user know whether he is on 2G / 3G / 4G.

Since usually apps are rather interested whether they are on Wifi or
cellular, change of cellular type (i.e. transition from 3G to 4G etc.)
will not trigger emission of the
"QNetworkConfigurationManager::configurationChanged" signal. The
cellular type check will only be performed if the user queries it by
calling the respective member methods (bearerType() and
bearerTypeName()).

Reading the cellular type takes around 1-2 milliseconds.

In addition, add new fields "BearerEVDO" and "BearerLTE" to the public
API for QNetworkConfiguration.
