Description:

Fixes Issue #249, Fixes #513; Fixes #514; Fixes #515;

• Fixed Dueling style not applying +2 bonus to one handed melee weapons.

  • Properly checks for weapons in only one hand
  • Properly only applies to non-two handed melee weapons

• Added ?damage-bonus-fns to damage modifier calculation

• Commented out melee- and ranged- specific damage bonus methods. Weird front end issues occurred when apply was... applied to those maps plus the map for the generic damage-bonus-fns

  • Properly utilizing the passed functions and conditions should eliminate the need for those other two methods.

• Fixed Bracers of Archery applying attack bonus instead of damage bonus

  • Added new method weapon-damage-bonus-mod which duplicates almost all the code from weapon-attack-bonus-mod. Combining them may be worthwhile, using a third parameter to set which bonus we want, or even both.

• Added boolean method bow? for checking if (long|short) bow, basically. Matches other weapon boolean checks.

• Incidental EOL change in weapons.cljc to LF
