Improve the format of widget message parameters

Browse Source 
In 5.1.3 we introduced the idea that the `event.param` variable could
optionally be a hashmap, allowing multiple values to be passed with the
message.

This change moves the hashmap to a separate `event.paramObject`
variable, allowing us to pass both a hashmap and a param string.
