Although it continued to build -- with lots of warnings -- the editor
quietly stopped working over the years. It would not come up on 64-bit
at all, and, even where it worked, the copy/pasting was broken due to,
apparently, some unwarranted assumptions about X11, that were no longer
true with modern Xorg.

This change makes use of a major patch, that provides for reasonably
warning-free compile -- which, by itself, fixes the crashes. Also
included in the patch are fixes for copy/pasting as well for parallel
building. (Awareness raised upstream.)

Because BR_Parser.y is among the patched files, bison is now needed at
build-time (found by KATO Tsuguru).

Bump PORTREVISION and take maintainership for the time being.
