Changes in ServiceScan screen: Better use of screen space

Changed ServiceScan screen layout in order make it use more screen space.
Added a title, passed FrontendInfo pixmap, network and transponder widgets from title panel to screen body.
Passed servicelist widget to right, to look more like other skin screens.

Minor changes in FastScanStatus, trying to fit the same ServiceScan layout.
(Couldn't make anything better, because FastScanStatus don't have servicelist widget)
