Bug: Impossible to define full msg from `ui-template

[joepavitt]

Description

Due to the underlying handlers for the this.send() function, it is expected that this will just send a value, and not a full msg object. We had a handler in place to prevent duplicate payload nesting, but this just surfaces that one value. Instead, we should treat anything sent via on-action or on-change as the full msg object.

This will require updating of pretty much every component, but will at least then enable the sending of a full msg object from `ui-template.

Okay I'm finally finding this issue after trying to set the topic on an outgoing message with no success. Could we at least in the meantime add this note to the docs?

One other point, if false or 0 are sent they are ignored so somewhere something is ignoring anything that does not compute as truthy.
