_planetstation.md

1. cd to your tgstation directory
2. mkdir data/planetstation
3. Place planetstation.py in tools/mapmerge2/
4. set PYTHONPATH=tools/mapmerge2
5. python3 -m planetstation _maps/map_files/*/*Station.dmm
6. Observe output in data/planetstation

If that doesn't work ping me on IRC or figure it out.
