Replace old spectrum analyzer by new one with higher resolution and many new features. Resolves #2847.
Spectrum Analyzer plugin
Overview
This plugin consists of three widgets and back-end code to provide them with required data.
The top-level widget is SaControlDialog. It populates a configuration widget (created dynamically) and instantiates spectrum display widgets. Its main back-end class is SaControls, which holds all configuration values and globally valid constants (e.g. range definitions).
SaSpectrumDisplay and SaWaterfallDisplay show the result of spectrum analysis. Their main back-end class is SaProcessor, which performs FFT analysis on data received from the Analyzer class, which in turn handles the interface with LMMS.
