v3.20

 - New file format for secondary and IP settings. This version of the firmware converts old to new.
 - Add geolocation: Display GPS coordinates in Destination and Last Time Dep displays. 114(DD notation)/115(DMS)/116(DMD) to enable/disable this mode.
 - Display mode (Room condition, World Clock, Geolocation) is now persistent (SD card required). Current mode is saved 10 seconds after activation (or upon fake-power-down or a controlled reboot such as when changing settings in Config Portal)
 - "Shuffle" setting changes are now saved (SD card required), "Shuffle" option removed from Config Portal.
 - Add option to *not* use GPS time; no one knows what happens after 2034/2038 when the GPS week counter rolls over, so although the firmware tries to correct wrong times, given I cannot test this in any way, it might fail and sync to wrong date/time.
 - Display MAC address (STA) on WiFi Configuration Page
 - Fiddle with timing for smoother Remote speed updates
 - World Clock mode: Display location name with time if both fit
 - Config files are now only written if actually changed which prolongs Flash life-span.
 - Add TC_NO_MONTH_ANIM compile-time option to skip the date-entry animation.  Might be desirable when using A-car displays: Given the "month" is just an ordinary 2-digit number (and no back-lit gel) the real thing probably switched on the entire line at once.
 - Code optimizations and fixes.
