- change absolute symlink bin/irc to a relative (in-directory) symlink
- change PLIST to include the bin/irc link instead of creating it, so
pkg_info -Lq matches what's on disk
- change ircII's Makefile.in to use our BSD_INSTALL_* macros, and now
strip binaries when installed (if BSD_INSTALL_PROGRAM does)
- show a confirmation message about compressing help files, and use
xargs instead of individual gzip processes for speed
- remove ircII.motd as well as ircII.servers at pkg_delete time
