xbbs 7.22 update

[Sanford 'Sandy' Zelkovitz]

I have noticed that there have been some problems compiling version 7.22
on some SysV systems. It seems that some systems do not have a
subroutine called logname(). You can do one of two things:
 
1) Download 7.23 which makes the code compilable on these machines
2) Modify the subroutine usenet() by replacing logname() with
   getlogin(). The only real difference is where it gets the login name.
   You will find that logname is mentioned twice: char *logname()
   and in the strcat function.
