Change the column name of longitude value from "lon" to "lng"

Recently trying out geo_field module and doing some integration with geo-spatial service like Google Map and GeoNames.
It is found that both Google Map and GeoNames use "lng" as the abbr. of longitude value, while geo_field uses "lon" in column name.

As "lng" seems to be the more common abbr. used for longitude value,
I would like to propose to change the current column name of longitude value in geo_field module to "lng".
I believe this would help to make the module more coherent with other services.
