Adding Carlo's Launcher Linux build and upload scripts to the
repository.   These currently sit in Carlo's home directory
on cvl.massive.org.au.  To use them, you need to install your
public key on all 6 of the Launcher's Linux build machines
in /root/.ssh/authorized_keys, and add the private key to
your SSH Agent, then ssh to cvl.masive.org.au with
agent-forwarding enabled (ssh -A).  I don't think these
build scripts really need root access to any of the six
build VMs, but they do use the root account on those VMs
currently.
