Use .env mode files, and kirby in subfolder

[Small-Systems]

1. Reformatting of vite.config so that .env mode files can be loaded, using loadEnv from Vite, rather than dotenv.
2. Modified VueKit.php; changed the url returned in the functions assetProd, preloadJson, preloadModule.

The purpose of 2, is that when kirby is in a subfolder the urls will resolve correctly. This is not specific to your install, but I have kirby running in a subfolder on my testing server i.e; dev.domain.com/project.

Hi, I don't see any comments, where should I be looking? (I've never done a PR before) Thanks, Luke

You should see them above, related to the code changes:

That's weird, my conversation looks like this:

My bad, didn't request the changes…

Hi there, I have manually merged your feature in 7e4c385, because your feature to deploy Kirby in a subfolder is a separate PR and will have to be tested thoroughly, so it won't break existing installations. Would you mind creating a new PR, thanks in advance!
