supplydrop bulk crate

Summary

SUMMARY: Content "adds a bulk shipping crate possibility to the supplydrop map extra"

Purpose of change

Provides a supply crate with a bulk package of a one item. So, for example, you get 128 units of dental floss or 32 voltmeters.

Describe the solution

Two lines were added to map_extras.cpp with the intended effect of making mil_food return only 30% of the time (down from 40%) and mil_bulk return 1 in 10.

mil_bulk:

  {
    "type": "item_group",
    "id": "mil_bulk",
    "//": "A bulk of uniform goods all of the same type likely found in a shipping crate",
    "subtype": "distribution",
    "entries": [
      { "item": "mil_mess_kit", "prob": 10, "count": 32 },
      { "item": "voltmeter", "prob": 10, "count": 32 },
      { "item": "drivebelt", "prob": 10, "count": 64 },
      { "item": "grapnel", "prob": 10, "count": 32 },
      { "item": "string_floss", "prob": 5, "count": 128 },
      { "item": "toothbrush_plain", "prob": 5, "count": 128 },
      { "item": "sm_extinguisher", "prob": 5, "count": 16 },
      { "item": "fire_ax", "prob": 5, "count": 16 },
      { "item": "manual_stabbing", "prob": 5, "count": 64 },
      { "item": "manual_rifle", "prob": 5, "count": 64 },
      { "item": "m17", "prob": 3, "count": 32 }
    ]
  },

Or, simplified, mil_bulk is a 1d7 roll on this table:

1. mess kit
2. voltmeter
3. drivebelt
4. grappling hook
5. dental hygiene
6. fire response
7. mil training manual

Describe alternatives you've considered

I wanted to this bulk crate to contain only one type of item, but as it stands now it will be paired with another item from the mx_supplydrop switch. There is 1 in 100 chance that a crate will contain two bulk items. It would be better if case 1 (mil_bulk) meant that only one item was generated. I think this could be achieved by putting int items_created = 0; inside the switch, and then setting case 1 to int items_created = 1; but didn't want to muck too much up.

The diversity of possible items in mil_bulk could be increased.

The bulk items could each be placed in boxes or together in some sort of cellophane warehouse packaging to simulate a shipping container (packing peanuts?).

Additional context

I believe there is no way for this item group to use existing item groups in order to get a better diversity of items. Because 32 instances of an item group will not return 32 instances of one item, but instead a variety of items from that group.
