Mk/Uses: always use colon for build/run suffix

Most USES use a colon for build/run(/test) suffixes. Change kde.mk,
qt.mk and pyqt.mk to do the same, and update all ports using that.

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.

archivers/quazip: update to 1.2, latest upstream

Release notes are here:
	https://github.com/stachenov/quazip/releases/tag/v1.2

There are a handful of internal changes that don't affect us
(allowing QtZip, for instance) or don't show up in our use of
quazip (-lz in pkgconfig file). There's one relevant change
to close() that **might** affect consumers, but then I'd expect
bug reports from the consumers about failures on load/save.

While here, move the libraries needed only for testing to _build.

Bumping PORTREVISION of consumers.

emulators/emu64: extend patch to fix an issue with OSS

This update is require to unbreak the port under FreeBSD.
The issue was reported to upstream and the fix will be available in future
releases.

Background: In the upstream issue, it was revealed that the whole C64 emulation
depends on the audio stream (for best sync) and initializing the audio stream
failed when the SDL backend was OSS, because it needs a fragment size that is a
power of two. The attached patch is the minimal change to 5.0.18 from the
upstream commit that solved the problem.
