Import znc-1.0 as wip/znc.

ZNC is an advanced IRC bouncer with IPv6 and SSL support.

This package is _almost_ complete. This means:

I am building packages using NetBSD-6.0.1-amd64. So far, i've been unable to enable python support for znc, using pkgsrc or not. Actually, it fails in 2 ways:

1) it does not pass the configure stage with only PKG_OPTIONS.znc+=python, you'd have to specify at least 1 other option.
2) even using two PKG_OPTIONS, the build always fails like this:
Compiling modpython/znc.pyc...
Shared object "libpython3.1.so.1.0" not found
gmake[1]: *** [modpython/znc.pyc] Error 1

I was hoping that through exposing this package to a greater audience, these issues maybe get addressed quicker.
added package 'znc' to Makefile.
