live stream needs to set sim start time before any location data is sent so script can still function when restarted when sim is running; renamed some variables for clarity; refactored message string to include time of day + sim running time

converted log timestamps into actual time using sim startup time as baseline

tidied up and improved load-times display, moved foratting of address into own method

added database function and logging of unknown or empty data points

new file geo_stream_static.pl; new command-line opt 'test' for outputting all log lines

Add GeoStream files only
