List extra settings parsing

[Emral]

Adding this block allows SMBX2's extra settings parser to properly populate arbitrary list extra settings. Here's one of those JSON files in practice, if you'd like to take a look. Unlike other extra settings, the "children" object serves as the template from which fields for each element are generated:

  "style": "groupbox",
  "title": "Crate Settings",

DRAT i just realized an oversight. The default values of the template is lost in the transition. Preparing a fix.

I've updated the pull request with the fix to the issue that defaults weren't properly copied to lua. I also set my visual studio to use spaces instead of tabs so if it's still using tabs, microsoft's being rebellious for some reason.
