update OpenVAS ports

[Любомир Григоров]

No one is maintaining it so I am writing here. Current version in ports is
2.0 (very outdated). Current live version in 4.0.

OpenVAS 4.0 is quite different so some of the old ports need to be removed
or reworked. As of now in ports are these:

security/openvas-client 2.0.4_2
security/openvas-libnasl 2.0.1_2
security/openvas-libraries 2.0.3
security/openvas-plugins 1.0.7_2
security/openvas-server 2.0.2_2

The new pieces are:

Libraries 4.0.3
Scanner 3.2.3
Manager 2.0.2
Administrator 1.1.1
GSA 2.0.1
GSD 1.1.1 / 1.2.0

They can be downloaded directly from http://www.openvas.org/ under the
download section.
Each has to be installed on its own.

Cheers.
