Add to Startup - add_startup(string $name, string $file, string $function, string $module,
			int $min_level, int $enabled)
This adds a function to be called at startup. These are the parameter descriptions:
$name - The function needs a name that can be displayed in the control panel
$file - Which file is going to need to be included to call this. Note, don't make this a file
	that your module will include, as it will result in an error. This is a feature, 
	not a bug.
$function - The function that is to be called. This function can return a string and other modules
	or the base can decide to use it if it chooses.
$min_level - The minimum level a user can have before the function will be called.
$enabled - You'll probably just want this as 1, but if you don't want in enabled by default, 
	set it to 0
