xbill: init at 2.1

Old game, once more popular than Quake (but not Quake Ⅱ).

From the homepage:

Ever get the feeling that nothing is going right? You're a sysadmin, and
someone's trying to destroy your computers. The little people running
around the screen are trying to infect your computers with Wingdows
[TM], a virus cleverly designed to resemble a popular operating system.
