[SyncEvolution] device configuration UI

I've pushed jku-configuration-redesign, which is rebased on top of mb9216. It includes initial UI for device configuration. It's quite rough around the edges, but I thought I'd get it out there ASAP... So, paired syncml-capable bluettooth devices should now be shown in a list of their own, right below services. When a device is expanded, the template selection is show. When one of the templates is selected, a normal configuration is shown (although some items such as uri text entries aren't shown for devices). Issues: * the configuration view is really ugly at the moment: way too much scrollbars and it might be overemphasizing devices (considering we won't actually support that many...). Nick and I need to do something about it. Suggestions welcome. * template selection is just a combo box for now. I'd like to have something like this: "X looks like the right configuration for your device". [ Yes, use X ] [ No, select from list ... ] * template names in UI (in the template selection) are useless at the moment: What I need is "Nokia 7210c" or "Symbian S60" or whatever our templates will end up covering. I could take the first string in fingerPrint property but I thought I'd poll opinions first.... * virtual sources are not shown because of bug 9535 (I have not tested the fix yet) Bugs might show up even in service configuration after setting up a device configuration: deciding what to show and when is becoming quite complex with undefined sources and virtual sources etc. ... -Jussi
