Add Warp Kit, Version 7.0 by Larry Wall

Warp is a real-time space war game that doesn't get boring very quickly.
Read warp.doc and the manual page for more information.

games/warp originally distributed with 4.3BSD-Reno, is back to the BSD
world via NetBSD. Its remnants were still mentioned in games/Makefile.

Larry Wall, the original author and the copyright holder, generously
donated the game and copyright to The NetBSD Foundation, Inc.

Import the game sources as-is from 4.3BSD-Reno, with the cession
of the copyright and license to BSD-2-clause NetBSD-style.
