We'll need something for the player location marker. Given that we'll be using images from the render service for Leaflet custom markers for everything else, I'd prefer to just find a royalty-free "you are here"/star/crosshair image to use for the player.
The commit referenced above adds a simple license-free crosshair icon, but it doesn't display well. It should probably be red, not black, with a drop shadow... see the custom icons tutorial
Use the files API and render service for map icons. We should fill the cache before Twisted starts (see the comment in server.py).
