One of today's changes:
- When Satellite basemap is in use, a new checkbox will be shown in Map Settings, allowing one to toggle an additional map overlay of public lands.
- Only appears when Sat is in use, selecting Topo also turns it off implicitly.
Added the unhighlightAll() and highlightFeature() families of functions, used to "highlight" the fishing areas and various markers when their info panel is shown. CSS was added to give markers a green glow effect when they're focused; fishing areas get a red outline.

removed initMapTouch() in favor of adding the code (which set up click events on the slideout info panel #page-map-info) directly into initMap()  This solves some issue that the X would not close the slide-out panel.
