Ability to set base URL path

[ivan-avalos]

Hello! Right now I'm trying to self-host this amazing thing I just discovered. Since my private networking setup lacks DNS, I can't use subdomains, so I tried to serve the app from a sub-path in Apache (e.g. http://localhost/notepad), but resources are always loaded from the root URL (e.g. http://localhost), and it doesn't work.

It would be very cool to have a flag that allows you to set the path from where your resources will be served (e.g. --base-path).
