Complete special attacks; Fix WeaponClass issues

* Adds a button property to a WeaponClasses styles, which maps a combat
  style to the button that was pressed in the combat tab.

* Adds full support for special attacks, with their config IDs and
  buttons.

* Adds the DDS special attack, along with the D2H special attack as some
  starting examples.

* Rename the "no_weapon" Weapon to "unarmed", so it shows up better in
  the UI.
