* Convert C++ types to Python types in API docs

* Translate some more types

* Convert return types that are STL containers

* Improved test case

* SWIG fix

* Reporter returns a bool instead of throwing an exception

Swigged python docstrings now include documented return values and type
information or their arguments. They are generated in numpydoc format.
Furthermore, all of the Python app layer docstrings have been changed
to numpydoc format. The filterPythonFiles.py script which helps to
generate the Doxygen Python API docs has been updated to reflect these
changes.

A previous commit had changed OpenMM_headers.i to OpenMMSwigHeaders.i without changing the corresponding include statement in OpenMM.i.
