Logged event types should be configurable

Hi,

it would be very handy if we could configure which particular event types gets logged. Currently every event gets logged by the spy listener which often results in huge amounts of console logs.

In most cases I would just like to see action logs per default and then enable more logs (e.g. reactions) on demand. This would be particular useful for ReactNative where you cannot rely on other devTools.

It would also be helpful to output timestamps for each log statements.

Regards.

PS: I think especially people coming from Redux are used to workflows like that, see Redux Logger: https://github.com/evgenyrodionov/redux-logger

Start by locating the spy listener and the code that emits console logs; the issue does not name files or tests. Review how event types are currently logged, then define done as configurable event filtering with action logs enabled by default, optional event types such as reactions, and timestamps on each log statement.
