added demo of app.py, ref-server
app py
Merge remote-tracking branch 'ctb/hw5-wsgi' into hw5
Moves content creation into app.py. A few tests (related with multipart data) fail because of the way im receiving the request. Might go away using ref-server?
 * Pages now actually use Jinja2 Templating

 * Refactored the server to conform to WSGI app standards
	Is also a lot cleaner, inspired by leflerja @ github
 * Deleted server.py, now using ref-server.py
 * Added a 500 Internal Server Error page
 * Wrote a few tests for the new app. Keeping old tests
	around so I remember what to test in the future.
