Technical changes in Piwigo 2.7

add_event_handler() 4th parameter

The fourth parameter of *add_event_handler* function was used to tell the number of parameters which will be transmitted to the callback. This is no longer used: all parameters given to *trigger_change* or *trigger_notify* are always transmitted to all callback.

But the fourth parameter is still used: if a string is given it will be used as a file path included just before the callback (with *include_once*).

// procedural
add_event_handler('init', 'my_init',
  MY_PLUGIN_PATH . 'include/callbacks.php'
// OOP with static method
add_event_handler('init', array('MyClass', 'init'),
  MY_PLUGIN_PATH . 'include/myclass.php'

If the 4th parameter is anything else than a string it is ignored.
