Added persistent event-listener system, module based.
Also added display_errors line, so errors don't get displayed verbose if php.ini is configured wrongly.
Deleted docs folder, that stuff is on a separate gh-pages branch now.
Deleted css folder. What was that even doing there?!
Changed the link to the docs in the README to the new url.
