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.

framework: Add new USES 'magick' for graphics/ImageMagick*

A new USES has been added to depend on ImageMagick.

	USES=magick

adds a LIB_DEPENDS on graphics/ImageMagick${IMAGEMAGICK_DEFAULT}.

If a specific version is required, use for example

	USES=magick:6        resp.     USES=magick:7

If only a build, run or test is required, use for example

	USES=magick:build    resp.     USES=magick:6,build,test

net/tigervnc-{server,viewer}: Update to 1.10.1

This is a security release to fix a number of issues that were found by
Kaspersky Lab. These issues affect both the client and server and could
theoretically allow an malicious peer to take control over the software
on the other side.

No working exploit is known at this time, and the issues require the
peer to first be authenticated. We still urge users to upgrade when
possible.

net/tigervnc-{server,viewer}: Update to 1.10.0

Lots of changes have been made since the last release, but the highlights are:

* The clipboard now supports full Unicode in the native viewer, WinVNC and
Xvnc/libvnc.so
* The native client will now respect the system trust store when verifying
server certificates
* Improved compatibility with VMware's VNC server
* Improved compatibility with some input methods on macOS
* Improvements to the automatic "repair" of JPEG artefacts
* Better handling of the Alt keys in some corner cases
* The Java web server has been removed as applets are no longer support by most
browsers
* x0vncserver can now be configured to only allow local connections
* x0vncserver has received fixes for when only part of the display is shared
* Polling is now default in WinVNC as that works better for most

net/tigervnc: Remove non-essential meta port

Reported by:	hrs [1]

[1] https://lists.freebsd.org/pipermail/svn-ports-all/2019-April/212975.html

Fix the issue tigervnc-server and -viewer cannot be installed together

when DOCS=on because both ports install LICENSE_FILE into the same place.
Also, following changes are made.

net/tigervnc-{server,viewer}:

- bump PORTREVISION due to plist & dependency change
- do build tests, it introduces unnecessary dependencies on fltk

net/tigervnc-server:

- add missing dependency on devel/m4
- remove unnecessary dependency on x11-toolkits/fltk

MFH:		2019Q2

net/tigervnc: separate port into -server -and -viewer

since usually people want to install either server or client on the same
box. Formerly, net/tigervnc had options to build & install vncviewer(client)
but vncviewer could not be installed alone. Server components was necessary.

Now TigerVNC server and viewer are completely separeted and can be installed
independently.
