Add language attribute in config

[ericrange]

There is no language attribute at all for the blog itself (except for the email templates)

[ericrange]

could be used for seo issues and etc... e.g. "(html lang={{lang}})"

if this is merged, i will do the necessary stuff on the casper theme to use this setting

Language is a user setting, not an environment config. You'll find a full set of planned work around translation is detailed here - which we're certainly looking for some assistance with: #3801

Hi @ericrange,
please have a read through our contribution guidelines, especially on how to raise feature requests.

Your PR is unlikely to get merged at this stage as this can easily be handled in a theme without having this config setting. Localisation will be implemented and discussed as part of #3801. It is too early to add language files and translations.
