Fix ksmserver launching shell scripts
Review Request #124838 - Created Aug. 20, 2015 and submitted
QProcess::startDetached doesn't work on shell scripts, presumably because it tries to daemonize them. Porting to QProcess seems to fix this. As KSMServer stays around forever this shouldn't result in any behavioural change.
added some shell scripts with
echo hello > /tmp/hello
was greeted pleasantly.
