Qubes R4.0

Seeing multiple issues.

First is that the grep on line 80 has a \| at the end while the output of qvm-ls -n has no | characters at all? When I run the command, it does not find my VM and exits.

local VM_LISTING_LINE="$(qvm-ls -n 2>>/dev/null | grep -E -m 1 "^${VM_NAME}\s+.+")"

After I alter the grep on line 80 so that the whole VM_LISTING_LINE variable is appropriately populated, I find that the TARGET_VM_IP and FIREWALL_VM_IP variables contain the strings `VM ${NAME} is running \n IP ${VMIP}" instead of just an IP address. This can be traced to line

Apparently the --quiet flag to qvm-check still produces output on R4.0 so redirecting all output to /dev/null sorts that out.
