Hello folks,

We in the mozilla team got tired of duplicating the same 50 lines of
code across 6 ebuilds, and decided to consolidate them inside one
eclass.

The eclass is specific to Mozilla products (no one else can or should use it).

It generates SRC_URI using a list of supported language packs
${LANGS[@]}, and exports src_unpack and src_install to install
language packs.

I'd love to have the attached eclass reviewed before I commit it. For
those using gmail, here's a web copy: http://i.cx/ahp
(git.o.g.o/mozilla)

Thanks!
