Daniel Martí 0d568ec2a4 change Run to allow many actions
This can simplify some common use cases, like running a few actions
directly, or running no actions at all. It's also an almost entirely
backwards compatible change, as all Run call sites should continue to
compile and work.

Leave Tasks, as it can still be useful for functions to return complex
sequences of actions as a single Action.
