WAIT 0. freezes script/terminal

[TDW89]

The command WAIT 0. if typed directly to the terminal locks you out until you cycle power (never completes and you can't Ctrl+C out.)
When in a script it freezes the script until you abort it.
This also happens if the value is negative.

hmm. That's... weird.

I'll have a look after I get functions checked in.

wait 0. should pretty much return on the very next update tick. It means wait N seconds, where N is zero ,so it should immediately become expired the next time it checks.

self-assigned just to ensure nobody else accidentally tries to work on it at the same time (even though I was bad and did the PR first).
