KGet frameworks branch

[Wolfgang Bauer]

JFYI:
I did manage to fix the multisegmentkio plugin in time (before the RC 
actually), and it wasn't actually a problem in the plugin itself:
https://cgit.kde.org/kget.git/commit/?id=60ecb4405e4175466073c5ae86894452ca7e9df5

And afterwards (as I expected ;-) ) the metalink plugin started to work as 
well (tested with downloads from kde.org and local .metalink files).
It did still have a "glitch" though, which I fixed as well:
https://cgit.kde.org/kget.git/commit/?id=ee59784466377321d157b4096d72a728af35e26f

Kind Regards,
Wolfgang
