[NEW] x11/contour (work-in-progress)

Hello,

I am working x11/contour, contour-terminal (http://contour-terminal.org/).
Here is the commit-4c71d0cce2e63a23859a1cf7b389dc9e872384a1 based ports,
work-in-progress version.

Contour-terminal itself is still developing for version 0.4.4.xxxx,
and this requires devel/boxed-cpp and textproc/libunicode package.

https://marc.info/?l=openbsd-ports&m=171961710727187&w=2 (libunicode)
https://marc.info/?l=openbsd-ports&m=171961232324802&w=2 (boxed-cpp)

Previously I posted these ports and I need ok for them to
work creating contour-terminal port smoothly.
