    documents: Add gdata_documents_entry_can_edit
    
    Entries on Shared Drives, or Shared with me are not always editable.
    Let's add gdata_documents_entry_can_edit to allow GVfsBackendGoogle to
    set file permissions accordingly. It would be nice to make also canDelete,
    canRename and canListChildren available, but it would require libgdata
    port to Drive API v3 unfortunatelly.
