Root .htaccess doesn't get installed when using the public webroot

[maxime-rainville]

There's an access .htaccess file that is meant to be copied to your project root when you are using the public web folder. However, it does not. The file exists, but there's no project-files extra directive for it in recipe-core's composer.json file.

This is probably because we're afraid it might conflict with the public-files one when you're not using the public web root.

This means that a project set up only with recipe-core (without silverstripe/installer) will not work out of the box with SSP if using the public web root.

Steps to reproduce

• Create an empty folder
• Add an empty public folder
• Initialise a composer file
• Require silverstripe/recipe-core

Expected result: recipe-core's root .htaccess has been copied to root of my empty project and my project is deployable to SSP.
Actual result: There's no .htaccess file in my project root and if I try to deploy it to SSP, I'll get a 403 Forbidden error.

The fix for this might involved updating recipe-plugin to always start by copying "public-files" and only copy the "project-files" if they don't conflict with the public files we just copied over.
