Merge branch 'analyzers'

This brings in proper fight outcome detection, which is nice and needed
for downstream applications (raidgrep/ezau).

Furthermore, this cleans up the CM detection a bit by moving away from
the "descriptive" trigger way to just having dynamically dispatched
methods for every log.
