docstring: Searches and loads ini, xml, php or inc file
  
  When no extension is specified the system looks for a file with the right extension,
  in the order: .ini, .php, .xml, .inc.
  
  .php and .inc files run within the context of this object and thus can access all
  $this-> variables and functions.
  
  @param string $fileName A filename in the include path
  @return mixed false if nothing was returned
