Sampo Savolainen f45474e688 Improvements on the FFT analysis tool
- Enable FFT analysis by default
 - FFT graph is now in cairo
 - The window is now a window instead of a dialog
 - Analysis window can be resized
 - The view can be switched between normalized 
   and an absolute value
 - The minimum and maximum values for a graph can 
   be shown
