Channel Spectral Display

Browse Source 
- Adds Channel Spectrum tab to display FFT of the audio output of the currently selected channel
 - Upgrades to JTransforms 3.0 FFT library
 - Adds three new context menus to main and channel spectral displays:
   -- Baseline - affects the vertical rendering baseline of the FFT
   -- Amplification - affects the vertical height of each FFT bin
   -- Averaging - affects how many FFTs are averaged to produce the display
