Subject: [PATCH] kaios: Hack out everything that needs dialogue boxes

They're proving to be a right nuisance and will probably require a
substantial overhaul to how they work across the entire JavaScript
front-end.  I don't think any of the functionality provided by the
dialogue boxes is critical, so in the interests of getting a minimum
viable product actually released I've disabled those features.

In most cases, this just involves commenting out bits of HTML.  The
"Custom..." menu item is added by C code, though, so there I've fallen
back to the standard Puzzles way to implement a nasty hack: an
environment variable.
