Switch from the stalled SourceForge 0.6.3 distfile to the FrauBSD
continuation on GitHub and take maintainership from ports@.
Drop PORTREVISION, fetch via USE_GITHUB, and link libXrandr via LDFLAGS
(with localbase) for live RandR panel geometry. Reinplace the shipped

Default-on FREEBSD_ORB option replaces the Super key glyph with the
FreeBSD orb (ports-only branding). Fn-layer XF86 media artwork ships
in the upstream 0.7.0 tag. Installs florence(1).
