This will make it work regardless of what the current URL happens to be.

Also move the telemetry setting into the options since we might as well
make use of it seeing as how we have to parse it for the base path
anyway.

In Firefox using the gzip mime type will (probably correctly) cause it
not to decompress while in Chromium it still will (incorrectly).

To make installing as a PWA possible. Fixes #1181.

Also make it a number.

It still won't work behind a base path, but if you're using a reverse
proxy you can just redirect to HTTPS yourself. And should probably
handle TLS termination there too.

For sockets I just needed to add back the proxy call.

Just a login form and a list of applications. No modals or anything like
that.

Now it should work whether you have a trailing slash or not.

This is mostly for development where VS Code might not have finished
compiling yet.
