Adding Regions Abbreviation

[GiuseppeLota]

Hello,

could be useful to add the Region abbreviation on the geojson/limits_IT_regions.geojson like "LOM" for Lombardia or "LAZ" for Lazio?

Hi, those abbreviations aren't part of any national or international standards, as far as I know. So I would rather not insert them within the data.

If you know of any references to a national standard, containing them, please let me know an I will work on inserting them into the data.
