 * Hi again.
 * Upon activation of this plugin I got a PHP Warning: `array_merge() [function.
   array-merge]: Argument #2 is not an array in .../public/class-advanced-custom-
   tooltips-public.php on line 74`. It didn’t happen again, only when I activated
   the plugin. Probably the constructor was called before the options have been 
   generated.
