Map: Height Maps

[dmnt]

If there's anybody interested in helping it'd be much appreciated. Some things to consider:

• User manual
• Testing
• Debugging

Especially some help file on how to enter coordinates, how to use the web app (entering coordinates on decimal format, rotating map, placing the grid on current location, what do all those buttons do etc.)

The map download system is getting pretty much ready soon, but will need some testing.
