MultisegKIO now use KIO::Get for the segments and KIO::file for the local file.
this should fix many problems with http redireccions and so. ftp also works now.

I make a segmentfactory class that handle the segments and olso can be used in the metalink plugin

now we pass a QList<KUrl> to the MultiSegfile_copy funtion. i'm planing to make a search funtion to return an KUrl List. any help or idea is welcome :)
