A very big change. It grew and grew locally.

- Make kdedglobalaccel more dbus aware. Needed for the global shortcuts contexts.

- Substitute the QStringLists with KGlobalShortcutInfo

- Register components with dbus too.

- Add kdedglobalaccel and component interface and xml files because the code generation is currently not possible

- Depprecate all methods using the QStringList interface of KGlobalAccel. Some of this methods will not be replaced. I do no plan to expose the internal api for the global shortcuts kcm any more. The kcm will use the new dbus interfaces completely.
More smaller steps follow.
