commit 6a24f6813bde2e42b0a05b949eaf22c9c95a7851

    libnm-gtk: new 'nma_mobile_providers_find_for_mcc_mnc()' method
    
    This new method of the API takes care of looking for a specific
    'NMAMobileProvider' given a MCC/MNC string.
    
    Originally developed as 'find_provider_for_mcc_mnc()' in
    'src/applet-device-gsm.c'.
