Checks if an artifact has been collected or not. This could be useful for mapmakers interested in making players complete their maps sequentially, or adding bonus effects for completion of previous maps.

if (ArtifactCollected("ae77e9661cd249cba8a5505e6c435247"))
	#Shield Key from Jojo.  Jojo give access to Beams.
	SetBuildLimit("BEAM" -1)
