Fix Makefile wildcard not matching ###.subtype.html files.
Added back some newlines for us poor humans.

They're stripped out by the Makefile anyway, so those 5 extra bytes per
file won't kill anyone.
Bring down.html and reallydown.html into Makefile-land.
Make it possible to turn off compression for 504.reallydown.html.

The JS in it doesn't like newlines, so we need to turn "compression"
off. Maybe we can add a smarter compressor later. Maybe it really
doesn't matter.
Add 403.nossl variant.
403.nossl style changes recommended by @chromakode.
Set appropriate alt texts for images.
