A lot of changes.

First of all, a php.ini file that makes Pulsir works great :D
Also, replies now make more sense and show a post preview and author,
as well as threaded replies. They’re a seperate function now.
User avatars on p.php now don’t depend on api.pulsir.eu.
I also started working on a new debug mode bar showing all sorts of
useful things :)
cms_class.php is now mostly properly indented.
