	 * Adds or updates a post-installation message (PIM) definition for Joomla! 3.2 or later. You can use this in your
	 * post-installation script using this code:
	 *
	 * The $options array contains the following mandatory keys:
	 *
	 * extension_id        The numeric ID of the extension this message is for (see the #__extensions table)
	 *
	 * type                One of message, link or action. Their meaning is:
	 *                    message        Informative message. The user can dismiss it.
	 *                    link        The action button links to a URL. The URL is defined in the action parameter.
	 *                  action      A PHP action takes place when the action button is clicked. You need to specify the
	 *                              action_file (RAD path to the PHP file) and action (PHP function name) keys. See
	 *                              below for more information.
	 *
	 * title_key        The JText language key for the title of this PIM
	 *                    Example: COM_FOOBAR_POSTINSTALL_MESSAGEONE_TITLE
	 *
	 * description_key    The JText language key for the main body (description) of this PIM
	 *                    Example: COM_FOOBAR_POSTINSTALL_MESSAGEONE_DESCRIPTION
	 *
	 * action_key        The JText language key for the action button. Ignored and not required when type=message
	 *                    Example: COM_FOOBAR_POSTINSTALL_MESSAGEONE_ACTION
	 *
	 * language_extension    The extension name which holds the language keys used above. For example, com_foobar,
	 *                    mod_something, plg_system_whatever, tpl_mytemplate
	 *
	 * language_client_id   Should we load the front-end (0) or back-end (1) language keys?
	 *
	 * version_introduced   Which was the version of your extension where this message appeared for the first time?
	 *                        Example: 3.2.1
	 *
	 * enabled              Must be 1 for this message to be enabled. If you omit it, it defaults to 1.
	 *
	 * condition_file        The RAD path to a PHP file containing a PHP function which determines whether this message
	 *                        should be shown to the user. @see FOFTemplateUtils::parsePath() for RAD path format. Joomla!
	 *                        will include this file before calling the condition_method.
	 *                      Example:   admin://components/com_foobar/helpers/postinstall.php
	 *
	 * condition_method     The name of a PHP function which will be used to determine whether to show this message to
	 *                      the user. This must be a simple PHP user function (not a class method, static method etc)
	 *                        which returns true to show the message and false to hide it. This function is defined in the
	 *                        condition_file.
	 *                        Example: com_foobar_postinstall_messageone_condition
	 *
	 * When type=message no additional keys are required.
	 *
	 * When type=link the following additional keys are required:
	 *
	 * action                The URL which will open when the user clicks on the PIM's action button
	 *                        Example:    index.php?option=com_foobar&view=tools&task=installSampleData
	 *
	 * Then type=action the following additional keys are required:
	 *
	 * action_file            The RAD path to a PHP file containing a PHP function which performs the action of this PIM.
	 *
	 * @see                   FOFTemplateUtils::parsePath() for RAD path format. Joomla! will include this file
	 *                        before calling the function defined in the action key below.
	 *                        Example:   admin://components/com_foobar/helpers/postinstall.php
	 *
	 * action                The name of a PHP function which will be used to run the action of this PIM. This must be a
	 *                      simple PHP user function (not a class method, static method etc) which returns no result.
	 *                        Example: com_foobar_postinstall_messageone_action
