Resolved issue in CRC-CCITT correction method. Added CRC error detection to PDU header block in the message framer, so that we're sure that the number of follow blocks is correct while we're capturing symbols/bits. Set the TDU message error correction to Pass since the CRC is calculated within the message framer and no errant NIDs (TDU) are passed.

Memory/CPU performance improvement and Audio/Mixer source restructuring
...
Converted to use float primitives and to keep samples in buffer format until the sample rate is decimated to 48kHz.
Added new non-recursive, CIC decimation filter -- untested
Updated sound card/mixer input source management. Now testing for mono/stereo support for each card and limiting channel choices accordingly. Separated the mixersource into a ComplexMixer and and SimplexMixerSource. The ComplexMixer is used for sound card based tuners like the funcube. The SimplexMixerSource is used for demodulated sound card inputs.
Interfaces for sample handling - standardized on using 'Complex' to indicate I/Q samples and 'Simplex' to indicate demodulated float samples. The processing chain now accepts either a decimated (48k) list of complex samples from a tuner channel source, or a 48k simplex buffer (array of demodulated float samples).
Resolved issue with HackRF tuner not applying tuner configuration information.
