Update BM for condensecrits, sumdamage, fix condense damage on kick/guard, update version/author

1. condensedamage now (more) correctly handles kicks and guards (rolls them up)
2. new option condensecrits will roll normal damage and criticals into a single "critical hit" message
3. new option sumdamage will if turned off, when combined with simplify, condense battle messages into a single line.
current behavior (sumdamage = true (default))
[3] Snicky 600 hit -> Blanched Mandragora
new behavior (sumdamage = false)
[3] Snicky 100, 200, 300 hit -> Blanched Mandragora

If combined with condensecrits the message would look like
[3] Snicky 100, 500!, 300 critical hit -> Blanched Mandragora

4. Updated BM version to 3.12 to reflect this week's changes, added myself as "maintainer" to the author string, with Byrth's permission.
