(Properties) Create a new actor using a Property::Map & event-thread-only default properties.

[Problem]  1) Cannot create an actor from a Property::Map.
           2) No mechanism of having event-thread only properties within Core.
[Cause]    1) Not available.
           2) Not available.
[Solution] 1) Create a method which creates an actor from a property map and vice versa.
           2) Added mechanism which checks whether a property can be used as an input to a
              constraint.
