[BUG] Submaster Sneak Time Cannot Accept Delay

Starting in 3.2.0 channel sneak times can accept delay in their syntax, but submaster sneak times cannot.

`Chan 1 @ 50 Sneak 10 Delay 30` is fine, but `Sub 1 @ 50 Sneak 10 Delay 30` is an error. I think sneak's syntax should be the same across all targets.
