Parse dart skill -> target

[Veracity0]

1. When we see a dartboard in fight.php, parse the various sectors and create a skill -> part map.
   Save it in _currentDartboard: "7512:arm,7513:wing,7514:leg,7515:head,7516:butt,7517:torso", for example.
   Since scripts have to split that on commas and pull the tokens from the left and right sides of the colon, they can make a skill->part and/or a part->skill map, as needed.
2. Stationary Buttons installs skill buttons for all combat skills on the skill dropdown. Apparently dart skills appear there, so, no extra parsing is needed to make those buttons. However, now we map "Darts: Throw at %part3" to "darts: throw at butt", if that is what the mapping is this fight. We re-parse every round, so even if KoL changes the mapping, we will pick it up.

Maybe coming in a later PR: session logging.

Round 1: Veracity casts DARTS: THROW AT %PART3!
Round 2: smut orc screwer takes 918 damage.
Round 2: Veracity wins the fight!

and

Round 1: Veracity casts DARTS: THROW AT %PART1!
Round 2: War Frat 500th Infantrygentleman takes 397 damage.
Round 2: Veracity wins the fight!

How about if we map the %PARTX to the part we threw at?
Perhaps allow "throw at butt" as a CCS action and map to the correct skill, whatever it is, at run time.
And verify that deleveling, stat gains, whatever, log correctly with dart skills.
