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.

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.

devel: remove 'Created by' lines

Popular high-performance JSON framework for .NET
* Flexible JSON serializer for converting between .NET objects and JSON
* LINQ to JSON for manually reading and writing JSON
* High performance, faster than .NET's built-in JSON serializers
* Write indented, easy to read JSON
* Convert JSON to and from XML
* Supports .NET 2, .NET 3.5, .NET 4, .NET 4.5, Silverlight, Windows Phone and
  Windows 8 Store

The JSON serializer in Json.NET is a good choice when the JSON you are reading
or writing maps closely to a .NET class.
