move autoloader functions out of engineapi class and into autoloader class
removed debugging
added method to clean $_SERVER['php_self']
uses new phpself class method for cleaning php_self
added exists() method to determine if a module's info has been loaded.
getInstance() is more flexible (can be called on other than creation now)
fixed (?) bug that prevented classes that have already been included, but the instructor not called, from using template tag replacements.
