Settings rework

[DaddelZeit]

This overhauls settings handling within KissMP. Previously, everything was stored inside kissui prepared for imgui widgets. This new solution notifies of changes passively via an extension hook and simplifies access to settings, instead of actively overwriting values from kissconfig directly.


This also introduces a new config save version. Previously, settings were stored like this:

{"base_secret_v2":" (omitted) ","show_drivers":false,"addr":"","show_nametags":true,"window_opacity":0.80000001192093,"enable_view_distance":false,"name":" (omitted) ","view_distance":300}

This was converted to:

{
  "data":{
    "perf.enable_view_distance":true,
    "perf.view_distance":200,
    "players.show_drivers":true,
    "players.show_nametags":true,
    "security.base_secret_v2":" (omitted) ",
    "ui.addr":"127.0.0.1:3690",
    "ui.name":" (omitted) ",
    "ui.window_opacity":0.89999997615814
  },
  "header":{
    "version":2
  }
}

Backward compatibility is given using header detection and converting formats if needed. Default values are provided in a separate config file and used by the code as fallback should a new version of KissMP run on an older config.


In addition to these changes, the settings tab within the main menu was overhauled. Previously, it looked like this:

This is the new layout:
