Title: Updating iframe action updated to force uppercase

The action passed into the xframe method is lowercase while the action detailed in the spec is uppercase. This is confusing when using the spec as a guide.

This converts any action string passed to uppercase so that "sameorigin" and "SAMEORIGIN" will both work.
