The Tor Browser cannot use -profile together with -app

When running a XUL application with -app, the -profile argument is ignored, and the default profile path is used. After the TBB migration that means the profile path becomes relative to the application.ini file thanks to the Tor Browser patches. This forces us to use a really ugly workaround to be able to run the Tor Launcher as a standalone application with a sane path for the profile (see config/chroot_local-includes/usr/bin/tor-launcher).

A good question is if the Tor Browser patches (e.g. the one that alters the default profile path) breaks this, of if -profile simply isn’t supported together with -app in upstream Firefox. If the former is true we should fix this, otherwise we can try to “improve” the Tor Browser’s patch so an environment variable can override the profile path, or similar.
