Rename ExternalMediaShape to IExternalMediaShapeBase

"I" because of interface.
"Base" because it's an interface of a base class
and because it's easy to mix it up with the inherited MediaShape.
(MediaShape also an externally rendered thing so
the name ExternalMediaShape doesn't make any
difference between the two classes)
