Started WSGI webapp

Started work on a WSGI webapp. For now, it runs off a
wsgiref.simple_server, so it can't really serve static content.
Therefore, code is minimally styled and internal, and all images are
external. The only really working part is search, and it's decently
fragile, but it works. Run from the command line with "python wsgi.py"
Small fix to pages and moved stylesheets to external source
Added support for exact matching ,hyphens in query, and custom error pages
Fixed basic search
Merge branch 'wsgi'
