UDM changelog
 TODO:
  - Plotter: access violation in Windows 10 when plotter maximized, workaround: resize plotter window smaller then restart.
  - SendGet: never recovers if power is lost and new requests are sent during 3second bootload time. A retry could be implemented that waits at least three seconds before trying.
  - Plotter: Add feature to show an arbitrary star altitude value (for Milky Way effect).
  - Plotter: add sun elevation to x axis.
  - GoTo: initial reading does not have valid position logged.
  - Vector plot: include options for; mpsas scale, cardinal directions, grid, lat, long, elev, start date/time, and end date/time.
  - GoTo manual coordinate entry not accepted unless Enter pressed on Mac.
  - Mac port conflicts between SQM/GFS/GoTo should have better error detection then disable connection.
  - First GoTo reading does not indicate the proper Zenith/Azimuth.
  - Plotter: Add location data (averaged) if it exists.
  - Plotter: Show local/GMT start/end times on plot.
  - Vector plot to Google map .kml overlay somehow.
  - pacificnew tz error requires fix in upascaltz.
