Automate corpses.json sorting

[victorfrye]

Is your feature request related to a problem? Please describe.
Every page load and render re-checks that the corpse list is properly sorted to ensure the list is ordered correctly with the projects to be killed first, most recently killed next, and those killed ages ago at the bottom. This is taxing to performance.

Describe the solution you'd like
Provide built-in sorting during the dev cycle. Provide a script that sorts the JSON data with the repository and call that automatically during before builds.

Describe alternatives you've considered
None considered yet.

Additional context

• Probably want to use PowerShell because love PowerShell, but may impose an environment dependency on those testing builds locally and not on Windows? Add README instructions if so.
