* Adds or updates a post-installation message (PIM) definition. You can use this in your post-installation script using this code:
*
* require_once JPATH_LIBRARIES . '/fof/include.php';
* FOFModel::getTmpInstance('Messages', 'PostinstallModel')->addPostInstallationMessage($options);
*
* 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 Text language key for the title of this PIM.
* Example: COM_FOOBAR_POSTINSTALL_MESSAGEONE_TITLE
*
* description_key The Text language key for the main body (description) of this PIM
* Example: COM_FOOBAR_POSTINSTALL_MESSAGEONE_DESCRIPTION
*
* action_key The Text 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 frontend (0) or backend (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
*
* When 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
*
