Added reference scaling to fftsink2. Default behavior is unchanged.
The new parameter 'ref_scale', defaulting to 1.0, represents a 0 dB
y-axis value.
Updated usrp_fft.py to display dBFS by setting ref_scale to 32768.0
and ref_level to 0. This results in the full 100 dB of dynamic range
being displayed.
Updated some gnuradio-examples to use the new parameter.
