Version 3.1 Released

Someone found a rather serious bug that could cause a segv in some circumstances, so I'm updating. There are other less serious fixes in this, but this is all bug fixes.

Another release will be coming soon, someone paid for the much-requested multi connection support and I have a pre-release out for this. It was rather hard to add, as you might imagine, as it touches a lot of stuff in the code. If you are adventurous, you can download ser2net-3.0-mc2.tar.gz or get the multicon-work-4 branch from git. This has all the fixes in 3.1, too. It would be great if others could test this before release. But some details may change depending on how things work out, so this is not a final release.
