Ocmulgee Mounds page updated

I updated the Ocmulgee Mounds page in the Ancient Architects of Georgia exhibit. I included new videos and new information including:

-Earth Lodge radio carbon dates and possible connection with comet appearance
-Mexican pyramid site of Xochimilco as possible location mentioned in Creek Migration Legend
-Removed erroneous translation of "tallula" as Chickasaw for "leaping waters." It's actually the Hitchiti word for "town."
-New picture of Creek chief showing similarity between his clothing and Chontal artifact clothing
-new information regarding skeletal remains featuring cranial deformation
