Fix total config collapse on improper update

Resolves the numerous issues here and in the discord of the update causing all MCDW weapons to vanish.

Accomplishes this by adding "dummy" values to the various "____Stats" classes. Doing this seems to appease Jankson, and allows for the config generation to actually go through.

Behavior 9.0.1 -> 9.0.2: If configs aren't updated, all weapons fail to register (because they are "disabled"), all weapons in players inventories vanish permanently.
Behavior 9.0.1 -> 9.0.3: Config updates with the isEnabled flags, registry is maintained, and items stay intact.

Also I recommend adding a pull request template. It felt a little cheeky to do so on a PR itself, but a simple example can be found in Fzzy Config source: https://github.com/fzzyhmstrs/fconfig/blob/master/.github/pull_request_template.md. Importantly, this notifies the PR-maker that they are agreeing to be bound by the terms of the softwares license (the TDL in this case)
