Can we please add support for single language tags in the dats?

The No-Intro naming convention allows for this in the case where the single language supported is different than the native / standard language for the region.

Two new games were just added that reminded me of this:

Call of Duty - World at War (Canada)   // Only supports French, but im not sure if "French" is the assumed language for Canada
We Sing Encore (Sweden)   // Only supports English
