Include interpolation of docstring content type.

Added a test for this.
Updated other language implementations.
The Obj-C implementation does not appear to support pickles so I didn't change it.

There is a generated parser change in the javascript. Not sure why - if it was accidentally left out before, or is environmental ( different versions of something?)
