ENH Add plotting to t-f beamformer example
Comment out overly restrictive frequency check

With this code uncommented the plot_tf_beamformer examples doesn't work,
because numbers of samples are sometimes slightly different for noise and data
time windows. Is this check really necessary? Maybe a different one should be
put in place or a warning issued instead of raising and error?
