:sig inport of Range is redundant

[emil14]

Range Case

Existing Range implementation has :sig inport just so we could write

:start -> 1..11 -> list -> println -> :stop

Instead of

:start -> { 1..11 -> list -> println -> :stop }

But that mean we always have to have something that will kick range. In that example that was the case so that was handy but is it worth it? Deferred connections are more universal in that regard and allow both cases - with and without separate kicker. E.g. imagine you wanna create RangeWrapper - you'll end up having all 3 inports :from, :to and :sig.

Other Syntax Forms

This problem is related to all #731 that might have kicker :sig to avoid deferred connections.

Constants

Related to #717

Maybe for constants having :sig inport makes sense, maybe they are really special case. As long as they are not "one-shot" things they do need something to trigger them (or defer, like now)
