Mk/Uses/apache.mk: Refactor after removal of older versions

apache22 and apache25 had been removed a long time ago however the
apache.mk file has never been refactored and is out of sync from the
file Mk/bsd.default-versions.mk. These changes refactors the removals of
the older versions. In addition:

- Move some keywords like USE_APACHE, USE_APACHE_BUILD, USE_APACHE_RUN
  from SANITY_DEPRECATED to SANITY_UNSUPPORTED
- Remove apache versions from ports Makefiles as currently there is only
  one available version in the tree. However the version checks are
  still valid and should work flawlessly whenever a new version is
  added. For example USES=apache:2.2+ are simply replaced with
  USES=apache. As currently there are no other versions available for
  test this could not be checked on it's own ground.
- Update FOO_USE=APACHE=yes to FOO_USES=apache
- Remove trailing whitespaces

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.

www: remove 'Created by' lines
