Added windows and added browser application

I added so when you double click on icon the window with app opens. Also browser was added. It is not google, funny thing google simply doesnt work in iframe. Also these windows are draggable from left side.
You can write a url and press Enter, then site will be loaded. In exaples can be seen Wikipedia and my other project - Authentication template )
