GameManager now Influences Dialoguer

Through NPC on mouse down.  Additional info added to the NPC and their
prefabs.  LaserPistol prefab was missing one data value, thus it was
changed.  Unity editor script added to allow for ease of relationship
editing for NPCs.  Relations determine what info is available when
talking to NPC's.
Added Door_Icon

Doors now have their own icon!  Yey.
Merged With Maria's Main Menu Code

Must test for bugs.
