Decentralized config, fixing of html5 audio, jsconfig in php!

A lot of new fixes…but im lazy, so lets make it simple:
- The chat config is now loaded off the ajax-chat config - so its
truely PHP-side configured.
- If you set AJAX_CHAT_CONF_UNI to true in the custom.php script, then
it will create a config.php in the lib folder like you are used to -
but it'll take all the entries from the config.d folder. For
productivity, set this to TRUE! But do NOT delete the config.d folder.
- Fixed a bug, and got a mysterious lag when the chat is starting…only
one message per second, I am unsure on how this is coming. But hey,
HTML5 audio works, regardless of the fact that we're running the config
off JSON - which appearently evaulates to nice JS, so i dont need
JSON.parse() =D.
