Currently it is complex to access civicrm hooks from Joomla Adding this will make it possible to use the Joomla plugin system to access the hooks.

CiviCRM has an extensive set of hooks taht are difficult to access from Joomla. Adding this file to the com_civicrm root and then including it using include_once(civicrmHooks.php) in the civicrm.php file will allow Joomla developers to use the native plugin system to work with Civicrm events.
Joomla plugins are observers, which in this case would watch for CiviCRM events and then notify the appropriate part of Joomla.

If this is implemented the default location for the custom hooks file should be change to this file for Joomal users.
