[PATCH 1/5] network: Add SignalStrength/Frequency properties to BSS interface

[James Prestwood]

This patch adds SignalStrength and Frequencies properties to the
BSS interface, which will provide more information for individual
BSS's.

[PATCH 4/5] client: fix get-bss command spacing/footer

[James Prestwood]

With the new SignalStrength properties the column width needed to
be updated. In addition there was no table footer which caused
the auto-refresh to not work correctly.

There is hardware that supports frequencies in the 60G range.  Might want to 
future proof this somewhat.

This specifically isn't fixing anything. I just needed to set the new 
BSS object prior to emitting the property changed signal. Technically 
this does change the function logic but we don't actually check the 
return of station_register_bss() anywhere, this could just be made into 
a void return I suppose if you'd like.
