Livecheck default option for perl5 group.

This option checks against CPAN search page. It considers the latest release
when there is a developer release.

As of now, a simple:
port livecheck categories:perl
reveals that:
- It doesn't work for 11 ports*
- 113 ports are outdated.
- 1 non-perl5 group based port is more current than freshmeat.

The other 193 ports are up-to-date.

* Those are:
- p5-csp
- p5-gnome
- p5-locale-gettext
- p5-mecab
- p5-net-ssleay
- p5-pathtools
- p5-razor-agents
- p5-term-readkey
- subversion-perlbindings
- svk
and
- p5-class-dbi (port version: 3.0.14, new version: v3.0.14)
