R820T Tuner Controller - expanded tunable frequency range to cover 3.18 MHz to 1782.03 MHz, although I don't currently have an antenna to test the lower HF frequencies.
...
- Resolved major issue where the tuner was only tuning half of the frequencies in a non-contiguous manner.

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

Resolves Issue #13 - R820T tuner was not accurately tuning requested frequencies. Updated the setPLL() method use PLL divider and integral enums to do away with the rounding errors being induced by Java that were inconsistent with the same method in the C++ librtlsdr code.
...
Discovered that the setTunerFrequency() method was not using the IF Frequency offset when tuning -- corrected.

R820T Tuner support added.
...
-Refined sample rate values for 2016 and 960 MHz rates, which were running much slower than advertised.
