games/vt100-art-and-animations: Add new port
These are VT100 Animation files, which are meant to be thrown up raw at
a vt100-compatible terminal. ANSI-ready terminals should do fine,
although the ideal venue is a Digital Equipment Corporation VT100
Terminal connected at 9600 baud. Many of these animations will fly by at
modern speeds, when they were meant to move much slower. The files
themselves are simply text with cursor movement instructions, deleting
and erasing the characters necessary to appear animated. Usually, they
represent a long hand-crafted process done by a single person to tell a
story. Some of these files may date back to the 1960's and 1970's.
