Overworld

Added a new overworld. The current idea is to have three separate dungeons each with some unique twist. You enter the dungeons in search for their Sacred Relic. Find them and escape with them before the cave crumbles. Back in the overworld you place your found relics on the "Relic Table" in the center of the overworld. Find all three and you will unlock the entrance to the "Temple of Glory".

Disclaimer:
* There is no Temple yet in prototype
* Currently the dungeons looks the same but with different relics.  Will change these dungeons next.
