[MM 0.6/nm-applet] Patches to indicate active LTE network connection in NM applet and other clients

[Marius Kotsbak <marius kotsbak gmail com>]

Attached patches to indicate in nm-applet to the user if the modem is 
connected to a LTE network. This is very useful for integrated combined 
3G/CDMA and LTE modems as they might not provide an LED to indicate this 
to the user as external USB modems often do.

Regarding backwards compatibility, if only the MM patch is in use, 
nm-applet will display a LTE connection as "GSM" (default catch-all), 
which I find acceptable. I assume other indicator clients also provide 
default values for unknown access technologies.

Nm-applet patch also add support for HSPA+. There should probably be 
created new icons for these also, but I have actually never seen the old 
ones in use either, so I wonder if there is a bug there too.
