  Log Message:
  -----------
  Improve Expression class and related code

Mostly cosmetic/readability/nullness etc. improvements.

The only functional changes are:

1. The "actor" is not set in variables if it's already there
(can be important in future "run under other actor" scenarios);

2. The wiring of SecurityContextManager to expressions/evaluators was
simplified, hopefully not too much.
