No versions for RISC OS and MSDOS on 286 or earlier machines this time -
the changes aren't particularly relevant for these and I'm busy this
week.

Here's the usual summary of changes in 1.0.23:

* Documentation: include 3d v3 file format description on MS Windows, MS DOS,
  and RISC OS too; include PNG graphics for manual on MS Windows; minor updates
  to manual.

* Prefer wxWindows 2.4 if it's available.

* (MacOS X version): detect MacOS X and look for MacOS X build of wxWindows;
  automatically add resource fork to aven binary.

* Disabled experimental support for Chinese (LANG=zh) - it isn't currently
  working and makes the printer drivers unusable on Chinese versions of MS
  Windows.

* (Unix version): tweaked debian packaging.

* cavern: Handling of "*:" at start of file wasn't fully fixed in 1.0.19.

Cheers,
Olly
