net/enet: Release port

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

net: remove 'Created by' lines

- Return my ports back to the pool.  I was unable to make any fixes to
  my ports in the past 3 weeks while ports were broken on any 10.x
  machines, which means I'm unable to maintain them.  So let people know
  that there's no available support for them until things are back to
  normal (which also means that anyone with spare time will be able
  to fix them without getting approval).

- Add port for net/enet

ENet's purpose is to provide a relatively thin, simple and robust network
communication layer on top of UDP (User Datagram Protocol). The primary feature
it provides is optional reliable, in-order delivery of packets.
