Include core functionality DLLs as part of main app embed

[gimmic]

Since Unchained will be only launching a select few DLLs, rather than present them as mods to the end user we should include them in the binary or binary deployment process.

They can be presented as installed with their versions(and links to the repos), but probably don't need to be listed in the mod registry or displayed in the same fashion as end user mods and maps.

I think this issue was made back when I was still playing with mod registry stuff. The way it works now that things are more hammered out is that the core DLLs are not listed, and the most up-to-date version of those core dlls are always downloaded.

I think this is preferable to shipping with the binary, because our address hooks/function signatures in those DLLs may need to change, and that shouldn't necessitate a user updating the whole launcher

Revisiting this might be a good idea since addresses are all offloaded to a config file in appdata. Updating the launcher to update the DLL might make for a better UX or even DX, even though it's technically wasteful. It would allow all the core update functionality to be bundled as "update the launcher". It may make releases here a little weird though, since a new release of the plugin would cause a new release of the launcher, even if nothing changed with the launcher itself.
