Strict focusing using Default Goal Selector.
We add a [SelectAlreadyFocused] constructor to [goal_selector] (read
"!") which causes a failure when there's not exactly 1 goal and
otherwise is a noop.
Then [Set Default Goal Selector "!".] puts us in "strict focusing"
mode where we can only run tactics if we have only one goal or use a
selector.
Closes #6689.
