Changelog	Added track length and track speed heatmaps. These can be turned on and off, and do not replace the original colour scheme for track length and speed. The heatmaps use a rainbow spectrum, which defaults to red=low but can be reversed if preferred. Long service references can now be displayed above each service. When the option is turned on, any train with a headcode exceeding the usual four characters will display the full headcode above the service. These only show where the reference is longer than four characters. Fixed a bug where if a blue route is followed by a green or red route, and a single segment of the blue route is truncated, the signal at the end would revert to red instead of according to the signal ahead.
