Include Templates and Bump Version to 0.1.1

I forgot to include the templates in setup.py, so httpbin would complain
and return a 500 when accessing views that require templates.  This
fixes that problem by adding them as "data" in setup.py and MANIFEST.in

+You can install httpbin as a library from PyPI and run it as a WSGI app.  For example, using Gunicorn:
