New configuration widget for people from other frameworks/libraries

[twinh]

For most people come from other frameworks/libraries, they are familiar with the configuration like below

return array(
    'domain' => 'http://example.com',
    'isSiteOpen' => true,
    'closeTips' => 'Sorry, we are maintaining, please wait a moment',
    'cacheDriver' => 'apc',
    'maxCacheTime' => 5,
);

It's not the recommend way to write configuration in widget, for we do not know which configuration is used in which class.
However, I think I should add a new widget to support this kind of configuration, it's really good for some application and when you work with others. :)

return array(
    'widget' => array(
        'xx' => 'xx'
    ),
    // name `config` may conflict with widget()->config
    'config' => array(
       // Move your old configuration here...
       'domain' => 'http://example.com',
       'isSiteOpen' => true,
       'closeTips' => 'Sorry, we are maintaining, please wait a moment',
       'cacheDriver' => 'apc',
       'maxCacheTime' => 5,
    )
);

Noted: website widget is good enough but have a bad name.
