Subject: Icon at the right of the urlbar that allows to add an opensearch
 engine

    introduce search icon
    description file downloaded after validation, not before
    icons updated when engine added
    add opensearch xml description files
    sync desktop file => fix add webshortcut
    use db_opensearch.json file to track opensearch engines
    create an opensearch description only when the engine support suggestions
    remove opensearch description when an engine is deleted in the webshortcut setting dialog
    popup: disable ok button when webshortcut is already used

Lionel Chauvin is the man having done this big, big, big work!!
I'm just merging ;)
