- Introduce a new scripting plugin which uses the new Kross::ScriptingPlugin class that allows to easily place scripting actions in the menus.
Also added two new dbus interfaces, SearchManagerAdaptor and SearchManagerAgentAdaptor, which can be reused as scripting interfaces.
These interfaces are a work in progress but it should allow to do things like check a site and export results/send email with one line of code

- Create a common shared lib which will be used by the part and the new scripting plugin

- Fix xmlgui merge issue
