Site uploader v1 more complete

At the serverside website, as long as a restaurant has been previously
added, new dishes (entered csv) can be dynamically added as a group and
will all upoad correctly with a new menu.  Note: the menu timestamp is
still broken, and the uploader always says it crashes after uploading
because it cant find "restaurant_foodmenu", still working on that but it
does upload.  Another partial website has been added- Cafe Sunflower
