Comment 2 for bug 1179624

The attached patch implements most of the points listed:

1- a different icon for bookmarks shown as web application.
    I'm not an icon designer so for the sake of the demonstration I've just picked GTK_STOCK_EXECUTE

2- the spilt in bookmark bar and the bookmarks panel of the Open and Run as web Application actions
    GTK_STOCK_EXECUTE is also used for the Run as web Application action.
    Note: To keep thinks coherent the patch changes the midori-view link popup menu the same way.

3- The reordering of these actions in the popup menu according the 'Show as web Application' flag value.

4- status bar text information on a selected item, showing:
     * for a folder: the number of child bookmarks and folders
     * for a bookmark: wether it is a web application or a regular bookmark and the bookmarked uri.
