Closes #1379.

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

Also fix padding not being respected when blocks exceed container
height.

We aren't providing binaries any longer.

Was looking a bit janky with the style changes.

Closes #1369.

Just sort of winging it.

For #1306.

Fixes #1308.

Also make it a number.

Fixes #1312.

Closes #446

If you want to use the last visited directory you should omit the
directory from the command line.

Fixes #1132.

As best we can, anyway.

Instead of the first.

Should make language packs work again.

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.

I temporarily removed this during the refactor so it needed to be added
back. This time I bundled it with the nbin loader code since it's all
related (will also make it easier to remove).

Just display the error message and exit. The stack trace isn't necessary
(since it's likely user error) and is potentially confusing.
