Add info about requirements for set bonuses

[squeek502]

EDIT: Note that this PR does not account for the case where bonuses are dependent on specific items being worn (add_func 1 in SetItems.txt). See this comment and the ones after it. Updated with Civerb's Ward's special case handled.

---

set_attributes_num_req and set_attributes_ids_req are companion arrays to set_attributes that stores the number of items that need to be worn or the set ids of the specific set items that need to be worn in order for the corresponding property list to be active. Only one or the other (set_attributes_num_req or set_attributes_ids_req) will exist in the json for any given set item. Only Civerb's Ward uses set_attributs_ids_req, every other set item will use set_attributes_num_req.

Example json output:

"set_attributes": [
  [{"id":43,"name":"Cold Resist +{0}%","values":[40]}]
],
"set_attributes_num_req": [3]

which means that set_attributes[0] requires >= 3 items (since set_attributes_req[0] is 3) of the set to be worn to receive those bonuses

Example json output for Civerb's Ward:

"set_attributes": [
  [ {"id":9,"name":"+{0} to Mana","values":[21]} ],
  [ {"id":45,"name":"Poison Resist +{0}%","values":[25]} ]
],
"set_attributes_ids_req": [1,2]

which means that set_attributes[0] requires set ID 1 to be worn (Civerb's amulet) in order to receive those bonuses, and that set_attributes[1] requires set ID 2 to be worn (Civerb's scepter) in order to receive those bonuses.

Another example of an IK set item:

  "set_attributes": [
    [
      {
        "id": 48,
        "name": "Adds {0}-{1} Fire Damage",
        "values": [211, 397]
      }
    ],
    [
      {
        "id": 50,
        "name": "Adds {0}-{1} Lightning Damage",
        "values": [7, 477]
      }
    ],
    [
      {
        "id": 54,
        "name": "Adds {0}-{1} Cold Damage",
        "values": [127, 364, 150]
      }
    ],
    [
      {
        "id": 57,
        "name": "Adds {0}-{1} Poison Damage over {2} Seconds",
        "values": [349, 349,150]
      }
    ],
    [
      {
        "id": 52,
        "name": "Adds {0}-{1} Magic Damage",
        "values": [250, 361]
      }
    ]
  ],
  "set_attributes_num_req": [2, 3, 4, 5, 6]

Updated to handle the special case of Civerb's Ward. Went with the first option mentioned in this comment. See OP for full description.

Note that currently this means the user will have to do some work when displaying these bonuses (check that the correct number of set items are being worn, or that specific set items are being worn). Alternatively, d2s could do those checks and only put the bonuses in the json output if they are actually active. Let me know what you think about that @nokka.

You want me to merge it? Not sure if it's possible for you.

[squeek502]

Sure, it's ready to merge. Any thoughts on this?
