Remove nested function BastaExtractContent

This fixes error "Using $this when not in object context"

The nested function BastaExtractContent was attempting to access $this
even though the function is declared as nested function within a class
function and not as a class function itself. Thus BastaExtractContent
had no access to the object instance $this.
