    Abstract WebKit string parsers into empathy-webkit-utils
    
    This file is currently optionally built, but if the logviewer is going to
    depend on WebKit, maybe that's a bad idea? Maybe we should just make WebKit
    required (this will probably happen when we require Adium themes in the future).
