Map editing guide

Use pkg/iceball/mapedit.

Arguments should be one of the following:

iceball -s 0 pkg/iceball/mapedit pkg/maps/inmap.icemap clsave/vol/outmap.icemap
iceball -s 0 pkg/iceball/mapedit 512 64 512 clsave/vol/outmap.icemap

You can optionally not specify that last filename,
but it is not a recommended practice.

For the first format, it is totally OK if the first two filenames are the same.

It is recommended that your maps are AT LEAST 128x(whatever)x128.

Quick notes:
- Water is the bottom layer.
- The layer above that is the ground layer, and is unbreakable.
- Intel/tent/player spawns are in the left quarter for team #1,
  and the right quarter for team #2.
- Tents will not spawn in the top quarter nor the bottom quarter.
- Nothing will spawn on water.
