Correct PoodleNTR mm patch

@VenVen, if a node exists, you have to use
@NODE[nodename] {
@key1 = newvalue1
@key2 = newvalue2
}
and if it does not, you do
NODE {
name = nodename
key1 = newvalue1
key2 = newvalue2
}

if it's a node inside a node, it goes @NODE[nodename] {
@node2[nodename2] { foo } }

Hope that clears it up! :)
