Add functionality to request refstring for new scanned services
Use referencestring to select service at scan results

To ensure it also performs well for renamed services
Satfinder: Ensure to free tuner at recursive close
Change satfinder plugin so it does not need changes in SatSetup

And remove the changes that where performed in SatSetup
Make compare with alternative compare in two ways
ChannelSelection: Improve some focus behaviours

In case you add or remove alternatives delete a service and only renumber
the OSD as it is really required.
ChannelSelection: Small improvement when add/remove alternatives

It should not be checked on the current service but on the last saved
service
ChannelSelection: Fix pipzap with parentalcontrol

Thanks Pr2 for reporting
Fix when exit channelselector when root is changed and service is the same.

Thanks Dima73
Upgrade of Dutch translations
ServiceScan: Streamline selection of service from scanned list
VirtualKeyBoard: Ensure input text is also unicode utf-8
Enable wrap around in choicelists
VirtualKeyboard: At least for now avoid GSOD for utf-8 ussues

For example with Russian texts we could have a GSOD. Now incompatible
charachters from the input string are ignored.
