[Discuss-gnuradio] Scaling output in fftsink2.py

fft_sink_c() and fft_sink_f() in fftsink2.py scale the output by the fft size using -20 log10(fft_size)

I think the intent is to make the output level independent of fft size.  Currently the output is a function of fft size.  See attached code (fftsink2_example.py). 

I think the scaling should be -10 log10(fftsize) .  Please see the attached suggested patch to fftsink2.py
