#10 Custom load time

[Colin McCormack]

The custom/ directory is loaded after the socket
listener(s) are set up. In particular, after https is
running.

This means it's impossible to intervene in any way in
the server setup.

It might be better if custom was loaded after the basic
code and configuration, but prior to actually starting
the server, to give customisations a chance to modify
behavior.

I guess one could make an argument that some
customisations could tweak security and loading them
after server start leaves a small window, but I don't
know of any actual cases of this.
