-Added a feature to link timeseries map data with lines.
-WIP on physical scale heatmap - everything has gone totally to hell.
-Got the real distance heatmap working. I want to select scale a bit more inteligently though.
-Finished reworking the heatmap. It now works off a real-world size in meters. There is a max pixel radius for performance reasons - this should be encountered infrequently with real-world use (and has a low chance of causing any hiccups). Legacy saved vises will use thier pixel values in meters at the moment.
-Reworked the way the heatmap scale selection works to be a base 10 exponential selector with a manual entry box for specific values.
-Changed the way map startup works to get rid of an ugly timer-based wait. Everything is based on proper google maps callbacks now.
-Tweaked checkbox handlers in map to be less error-prone.
