7455077cfa Spectrum/Waterfall display zoom feature - work in progress (issue #33)
Implements zoom in/out by mouse scroll wheel and by right-click context
menu.

Still have to add ability to drag spectrum left/right when zoomed in.

70e62ebb35 Adds airspy USB tuner support and updates the spectral display
component.

-Airspy supported with 10 and 2.5 MSps sample rates.  Additional
decimation may be added later.

-Spectral display updated to include smoothing and filtering options.

Note: the decimated output of a tuner channel from the airspy is
48,076.9 samples per second, versus the normal 48 kHz decimated rate.
This is 1.0015 times the normal rate and doesn't appear to impact the
decoders or audio processing.  Therefore, no fractional resampling has
been added.

ae0568ff3b Updated spectral display to used dBm scale and removed baseline/amplification items.
Updated sample handling code to use -1.0 to 1.0 float values throughout, to support P25 decoder and symbol filter.

4e0fd9b7b0 Channel Spectral Display
- 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
