Add more robust (but backward-compatible) plugin config system.

util.php: add common_config_section($main), as a companion to common_config($main,sub)
statusnet.php:
        * add public static getPlugins(), which returns array_merge(common_config('plugins','default'),common_config_section('plugin-list'))
        * use self::getPlugins(), instead of common_config('plugins,'default')
        * handle plugins that have a type other than "array" or "null" for parameters
pluginenable:
        * use StatusNet::getPlugins() instead of common_config('plugins,'default')
        * set $config['plugin-list'][$plugin_name] = 1
pluginsadminpanel: use StatusNet::getPlugins() instead of common_config('plugins,'default')
