This PR fixes ports/38588.
ECHO -> ECHO_CMD
Fix plist.
Removed WANT_GNOME, because the Gtkfrontend is buggy and unmaintained.
This was suggested bei Eric Cronin (ecronin@eecs.umich.edu)
Fixed IPv6 support. We have no libinet6 anymore. Spotted by Martin Proehl (e9926661@student.tuwien.ac.at). This fix was tested bei "s0ul" from OPN's #freebsd channel.
Switched to use autoconf because of the IPv6 patch.
Therefore removed patch-az and adjusted Makefile

In Case of Problems, you can get the hole port skeleton from http://oki.dynodns.net/~tilman/bitchx.tar.bz2

Fix: Remove patch-az.
Add new patch-configure:
