[Xtide-announce] minor updates to lots of stuff

[David Flater]

Minor updates 2020-06-28

The XTide, Congen, libtcd, and tideEditor packages have all been touched to perform some minor but messy maintenance.  Build scripts that were specific to particular flavors of Linux and to non-Unix platforms were moved into a new separate package, FunkyBuilds; configure scripts were patched to improve portability; old URLs were updated, and documentation nits were fixed.  XTide got a bugfix increment because some of the outdated URLs were in the source code; the other three packages are just re-releases.

FunkyBuilds includes a new build script for Ubuntu and an improved one for DOS.  A new DOS binary has been posted under Contrib.
