/** Initializes a plugin.
* This function is called from the plugin file, after the plugin class definition. It loads the plugin from the data given in argument, includes dependencies,
* loads the class, automatically binds the events to correctly named methods.
*
* \param $params Loading parameters for the plugin. This associative array allows these values :
* \li \b name : The name to be used for the plugin (i.e. the file name). String.
* \li \b className : The main class to be instancied for the plugin. String.
* \li \b dependencies : The dependencies the plugin needs for functionning. Array.
* \li \b autoload : To let know if the function has also to do automatic binding of events. Boolean.
* \param $manual Manual loading indicator. It permits the bot to know if a plugin has been loaded manually or automatically, by dependence.
* \return TRUE if plugin initialized successfully, FALSE otherwise (and throws many warnings).
