fix glitch in fft.c and add scripts to display data sets without temp file

- usrp/doall: new script to directly evaluate and plot data sets
- usrp/fft.c (fft_complex): don't square the magnitude
- usrp/plscan: if an argument name has the form title=name, use "name" as
  the file name and "title" as the title
