Proposal: adapt languages to international standards (i18n)

[daniel tygel]

Hi all,

    We are preparing Cirandas to be adapted to international metadata 
standards, and we had several issues because Noosfero uses non-standard 
nomenclature for languages. Normally, languages must be defined by the 
language and the country, such as pt_BR, pt_PT, pr_CI instead of pt.

    We would like to know if you would see problems if we migrate 
noosfero to use these standards. For the moment, we are using symbolic 
links in the po folder.

    Should we proceed and propose a merge request, or is there someone 
who thinks that this won't be good for noosfero?

    We are trying to upgrade cirandas today to rails 3 + responsive.... 
tension in the air :-)
