implement proper outcome for w1-w4

It turns out that `was_rewarded` is a pretty bad heuristic if you ever
kill a boss a second time per week (basically, was_rewarded=false does
not imply that the boss was unsuccessful). Therefore, we need a proper
detection of when a fight failed and when a fight succeeded.

This is the first batch that implements this as part of the Analyzer
trait for bosses of wings 1 to 4.
