[RFC] translation back-ports

It's time I think to start making the older branches of Squid more
compatible with the langpack translations.

The plan is to immediately:

  - merge back the templates directory contents as if it was a new language.
  - make those templates the default hard-coded language files instead
of English/* .

Two further steps needing discussion:

  - removing the old translations bundled with those branches. quite
outdated now.

  - best way to bundle the langpack with old branch releases. making
squid code a single download bundle again while keeping the langpack
updates a separate download built from 3-HEAD. Is it even worth it?

  - is it worth cross-porting the auto-negotiate feature to 2.7/2.8?

It's definately not worth back-porting the translation toolkit pieces
and .PO.
