v0.0.1.23

-Global var myPathList has been done away with. The paths are passed
down through the functions to scanFiles(). It was occasionally getting
reset by Plex randomly calling MainMenu(). Fixes issue #56
-Database files in the log no longer encoded for easier reading.
-Use Prefs[] framework instead of setting global vars.
-Prefs checking is now done in ValidatePrefs()
-getPrefs() is now logPrefs() as it only logs the current prefs.
-Global var PMS_URL is now using the Dict[] framework instead of being a
global var.
