Add script to update version numbers in various files

Hopefully I'll be able to keep them all wrangled now.

src/syncterm/updvers.sh

+#!/bin/sh

+# Files that need to be updated:
+# CMakeLists.txt - CMake packaging... obsolete, but present
+# Info.plist - macOS information
+# Manual.txt - Ugh.
+# dpkg-control.in - Debian Package information
+# syncterm.c - syncterm_version variable
+# syncterm.rc - Windows information
+# syncterm.spec - RPM package information
