*neutrino buttonbars: reworked painting of buttonbar in

channellist,
stringinput (also cleared some char format problems),
audioplayer,
bouqueteditor_bouqets,
bouqueteditor_channels,
bouqueteditor_chanselect,
bookmarkmanager,,
bouquetlist,
filebrowser,
epgplus,
epgview,
pictureviewer,
timerlist,
upnpbrowser

TODO:
This is still not a final solution. I would like to see buttonhandling in
own class for better integration and handling of window structure.
