Bug: Fix so we can keep using internal sdr-ip for testing
Bug: deviceNumber wasn't set when receiver  powered on
Added priority setting to threads
Changed GetQueueStatus to return bytes in queue
Added DeviceHealthValue and DeviceHealthString
SDR options button changes from green to yellow to red based on DeviceHealthValue.  Gets updated every time clock is updated
Updated ProducerConsumer to use timers instead of sleep
Added FTDI set buffer sizes
WIP:  SDR-IP works well, SDR-IQ runs through producer/consumer buffers still
Updated calculation for Consumer Producer intervals.  Set to 90% of ideal to give a little head room
Tweaks.  SDR-IP working beautifully, but SDR-IQ consuming free buffers.  Possible USB producer problem?  FTDI problem?
Still working on USB performance, consuming all free buffers despite lower sampling rate
Fix overflow color on sir options button
Tweak to help debugging usb read
More sdr-iq cleanup, still gobbling buffers
Put back logic to check for usb available bytes instead of blocking in read waiting.  Went from 60% cpu to 20% after this change
Added isRunning flag to workers
Update to work with current ProducerConsumer.  Consuming about 80% CPU, so still needs tweaking
Removed last internal device, 100% plugin now
Removed internal RFSpace device files, moved to archive directory
