Plugin Name: Jalenack's Wordspew
Plugin URI: http://blog.jalenack.com/ajax/
Description: A plugin that creates a live shoutbox, using AJAX as a backend. Users can chat freely from your blog without refreshing the page! It uses the Fade Anything Technique for extra glamour
Author: Andrew Sutherland
Version: 1.15
Author URI: http://blog.jalenack.com

// Version of this plugin. Not very useful for you, but for the dev
$jal_version = "1.15";
// The number of comments that should show up in one viewing.
$jal_number_of_comments = 35;
/*
==================// Important Info //=======================================
This file is called in three different places. First, it is called by Wordpress
so that it can display the jal_get_shoutbox function.
Secondly, it is called by javascript. Because it is called by javascript and not by wordpress,
normal plugin procedure won't work without directly calling the wp-config file in your root
directory. We cannot use the $wpdb object. So instead, we open up the config file, comment out
the bit about calling the rest of Wordpress, and then evaluate the config file to extract how to
access the database. We do all this so that the entirety of Wordpress is not loaded by each call
to the server, which would put great unneccessary load on the server and conflict with other plugins.
To differentiate between the two remote calls, I've used the $jalGetChat and $jalSendChat variables.
These two variables are sent by the javascript file as "yes". That way, the script will only perform
certain actions if it is called by the javascript file.
Thirdly, it is called by the wordpress admin panel, which allows users to edit settings for this plugin
