[Doxygen-develop] [PATCH] Fix alphabetical class list

[Frank R. <fra...@gm...>]

If you're using multiple prefixes in IGNORE_PREFIX, the alphabetical
list is basically whack (example:
http://crystalspace3d.org/docs/online/api/classes.php - prefixes are cs
i aws scf). The attached patch will fix the list to be sorted without
the prefix.

(Is this the correct place to send a patch?)
