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.

print/fig2dev: Add license text

The text of this license has been extracted from: configure.ac
and refers to all of fig2dev. It includes a list of historic authors
and contributors, and while not resembling a standard license, it is
clear that all rights to build, use, and distribute this software
without any restrictions is granted.

One more small cleanup, forgotten yesterday.

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories p

Add USES=xorg and USES=gl to ports in categories starting with 'p'
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

print/fig2dev: fix to build, needs some help to really use ghostscript

- GSEXE was not set during build, causing
  fig2dev -L pdf part.fig part.pdf
  to fail like this:
  sh: -q: not found
  Error in ghostcript command
  command was:  -q -sAutoRotatePages=None -dAutoFilterColorImages=false
-dColorImageFilter=/DCTEncode -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress -o
'part.pdf' -

New port: print/fig2dev

Fig2dev is a set of tools for creating TeX documents with graphics
which are portable, in the sense that they can be printed in a wide
variety of environments.

Drivers currently exist for the following graphics languages:
AutoCad slide, BOX, (E)EPIC macros, LaTeX picture environment,
PIC, PiCTeX, PNG, PostScript, Encapsulated Postscript, GIF,
IBM-GL, JPEG, PCX, MF (METAFONT), TeXtyl, TIFF, TPIC, XBM (X11
Bitmap), XPM (X11 Pixmap), and TK (tcl/tk).  Fig2dev can be
configured with a subset of these drivers.

This port will replace print/transfig after a bit of testing.
