Add property lists to Actors

Modified the Actor code to provide a list of properties needed by the
actor to perform a given operation.
Added a build() method to the parameter class so invokers can build an
operation and set its properties prior to starting it.
Added a "preprocessed" field to the parameter class so invokers can
indicate that the Actor need not perform any preprocessing steps.  Will
modify the actors, in a subsequent review, to observe the flag.
Added "properties" to Operation so invokers can set the properties.  Will
modify the actors, in a subsequent review, to use the property values
instead of the event context.
Tweaked a few Actors to get values using the "params" object instead of
reaching inside to the event object that it contains.

Addressed review comment(s):
- add prefix to other property names
