Avoid excessively connecting configuration properties in interactions

Some interactions connect properties to sub-interactions or other values, e.g. ArcMove's: runtime.connect(arcMove(from: from, to: to), to: tween.path). This only needs to be done once.

Closure of this task involves auditing our interactions for any runtime.connect invocations and ensuring that if they're connecting sub-interactions together that we're only doing so once.
