This should reduce the number of times users are prompted to install
pylab || scipy when they'd actually get away with functionality fully
contained in numpy and matplotlib.
This only solves the obvious cases. There's some usage of `pylab.mlab`
that would need more than 20s of consideration.

The FM preemphasis filter design now precludes the user from
inducing a pole on the unit circle at z = -1.0 and z = 1.0.
A pole at either of these locations makes the filter unstable and
useless: feeding back "+/-inf" into an IIR filter has no good
recovery.
Also provide a reasonable, maximally safe default of 0.925*fs/2.0
for the high frequency corner, fh. This keeps the slope of the
preemphasis filter looking reasonable sane in the whole band; at
least for tau=75e-6 and fs=48000.

Add working filters designs for the FM preemphasis Tx filter.
Rework the FM deemphasis Rx filter as it was easier to rederive
the transfer function, than to determine if the one in use was correct.

copy, head, skiphead, vector_map, and annotator blocks to use gr-blocks.

Also fixes up some other missing moves.

Also updating some Python blocks and examples to properly pull from filter and analog.
