Review Request: Adding "net usershare" suport for KSambaShare

[Alex Fiestas]

I just saw the commit, and when trying it the old
"Make sure that the Perl script 'fileshareset' is set suid root." appeared.

So I performed a grep in kdelibs and fileshareset is at least appearing 
in: kio/kio/kfileshare.cpp KFileItem::setShared method.

Also, the perl scrip is still there in kio/misc/fileshareset.

Cya and good work! can't wait to test this.
