Subject: Adds RSS auto-generation for files in 'site'

This commit adds rss_generator.py which contains the main logic for
indexing the site directory and generating a feed on startup. It serves
as a sort of ad-hoc database which is accessed when /feed.xml is
requested.

Also corrects various typos, README nonsense, and expands the config
options for RSS. Instances of './templates/site' have been replaced with
the general BASE_DIR variable in the siteconfig.
