Cloudspire Riser for Castle Mats

If you want to pack everything there currently is for [Cloudspire](https://boardgamegeek.com/boardgame/262211/cloudspire) into the main box (except the spire miniatures ofc), you have to abandon the plastic container for the map tiles.
This is a simple replacement for the "foam approch" CTG suggests.
The pictures should speak for themselves, I hope you like it.
