make all ports independent of which version of Perl is installed or the major one

[macintosh@…]

ports can be made independent of which version of Perl is installed or the major one by

1) setting a portgroup:
   PortGroup           perl5 1.0
2) change all hard-coded instances of perl5.12 and p5.12 to
   perl${perl5.major} and p${perl5.major}

But as pointed out in #34461 by Ryan, there are tons of ports that are hard-coded this way.

This mega-patch implements the above in all 104 affected ports

Incidentially, it thus also invalidates #34461 & #34357

This has been discussed on the dev-list starting with
​http://lists.macosforge.org/pipermail/macports-dev/2012-May/019263.html

!!!NOTE!!! if you run either script, you'll have to revert

lang/perl5
lang/perl5.12
