Mk/**ruby.mk: Switch from USE_RUBY=yes to USES=ruby

Switch from Mk/bsd.ruby.mk to Mk/Uses/ruby.mk

Notable changes are.

- Mk/bsd.ruby.mk is moved to Mk/Uses/ruby.mk.
- USE_RUBY=yes is replaced with USES=ruby.
- USE_RUBY_EXTCONF is replaced with USES=ruby:extconf.
- USE_RUBY_RDOC is replaced with USES=ruby:rdoc.
- USE_RUBY_SETUP is replaces with USES=ruby:setup.
- RUBY_NO_BUILD_DEPENDS and RUBY_NO_RUN_DEPENDS are replaced with
  USES=ruby:{build,none,run}.
- RUBY_REQUIRE isn't used anywhere, so removed.
- USES=gem now implies USES=ruby.

This is mainly the work of yasu@ at https://reviews.freebsd.org/D27863

I have just made some cosmetic changes and ran exp-run to test that the
tree is not in a BROKEN state.

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.

irc: remove 'Created by' lines

irc/rbot: mark broken with Ruby 2.2

mark ports that don't work with Ruby 2.3

PR:		205774

Update rbot to the new upstream from the 20150311 snapshot.

It now actually works with Ruby 2.0+.

This requires manual migration to fix the registry files. See the
UPDATING entry.

Cleanup plist

Remove trailing whitespaces from category irc

According to the Porter's Handbook (5.12.2.3.) default options must be added to
OPTIONS_DEFINE. This policy has been implemented only recently that's why we
have many ports violating this policy.

This patch adds the default options specified in the Porter's Handbook to
OPTIONS_DEFINE where they are being used. Ports maintained by
gnome@FreeBSD.org, kde@FreeBSD.org and x11@FreeBSD.org have been excluded.
