Grav in subfolder without site visitors ever knowing

@flaviocopes: thanks! I’ll give that a try.

@paulmassendari: not sure I can change the dns target directory due to the host being used. Moving Grav a folder higher would put it in webroot, which I’m trying to avoid.

@jmonroe: sorry to be a noob, but what changes do I have to make to system.yaml to get your rewrite rules to work? Looking through all of the settings there, it’s not obvious to me.

Thank you all!
