Language alias linker/installer/upgrade scripts

alias-link.sh
  This is a script set designed to be called via make/Makefile and setup
  language codes for those languages which it would be impractical to
  bundle duplicate translated files for.
  Relies on local environment tools to be detected by automake.

make install
  - now also calls generation of aliases after existing install.
    Provided in file aliases.

make upgrade
  - cleans out legacy files from pre-3.1 and replaces with symlinks
    to the new upgraded language codes.
    Provided in file alias-upgrade.
  NP: this is a destructive process and must be manually run.

Bundle aliasing scripts and Makefile to use them with the langpack.
