When a mod adds a dependency to its manifest (see #285), let it specify the order it should be loaded:

{
  ...,
  "Dependencies": [
    {
      "UniqueId": "EntoaroxFramework",
      "LoadOrder": "After"
    }
  ]
}

The possible values are:

• Before (default): load the dependency before this mod.
• After: load the dependency after this mod.

Split from #248.

There's no current demand for this feature and it would unnecessarily complicate mod loading. I'll close it for now; we can reopen or create a new issue later if needed.
