[syslinux] SYSLINUX 3.31-pre3 released

[H. Peter Anvin]

After thinking a bit of the multi-file support in 3.31-pre1, and 
considering a few users' feedback on the subject, I have made a couple 
of changes:

1. The dummy filename ~ can be used to mean "the main config file".
2. There is a MENU INCLUDE directive now.
