Reimplement FCF functionality

[perryhuynh]

Looks like the FCF functionality still needs to be reimplemented

[mrmin123]

Are you still running FCF? Please post the combat data from a combat node post-FCF if you can..

[mrmin123]

And the resulting kcsapi/api_get_member/ship_deck API response.

[mrmin123]

I've added some logic necessary for FCF, but am waiting on API responses to be able to finalize it.

The changes also have rudimentary support for #94, although it needs update to the config handler and GUI to be fully implemented.

5th ship in escort fleet taiha'ed, retreating with 3rd ship in escort fleet. Relevant portions in json responses are as follows.

kcsapi/api_req_sortie/battleresult; contains api showing 1-based idx for ships to escape and ships that can escort:

{
  "api_data": {
    ...
    "api_escape_flag": 1,
    "api_escape": {
      "api_escape_idx": [
        11
      ],
      "api_tow_idx": [
        9,
        10
      ]
    }
  }
}

kcsapi/api_req_combined_battle/goback_port; might as well be empty:

{"api_result":1,"api_result_msg":"\u6210\u529f"}

kcsapi/api_get_member/ship_deck; retreated ships have fuel value of 0:

{
  "api_data": {
    "api_ship_data": [
      {
        ...
        "api_fuel": 0,
        ...
      }
    ]
  }
}

kcsapi/api_req_combined_battle/battle; no changes to reported HP:

{
  "api_data": {
    ...
    "api_escape_idx_combined": [
      3,
      5
    ],
    ...
  }
}

Outstanding question(s):

• What is the dict key for the primary fleet equivalent of api_escape_idx_combined?
