Add a Joomla! helper to make it simpler to access the API from Joomla components.

This helper file should be placed in administrator/components/com_civicrm/helpers.

It provides the basis for accessing the CiviCRM API throughout the Joomla! applciation.

For example I am attaching a file that is part of a Joomla! plugin that uses the helper to put the contact_id of the logged in user into the session. (civicontact.php).

This is used in the second attached file (mod_my_civigroups) in a frontend module that displays the groups for a logged in user.
