Proposal to change the code for Montenegrin

Dear colleagues,

Montenegrin appears at the moment with "SLA" code in XTRF. As there is no official ISO 639-1 code for Montenegrin, we don't have an official obligation, but SLA sounds very generic and misleading (like general "slavic" it's a bit unfair to the identity of Montenegro that is a candidate country to the EU), plus it doesn't fit with the 2-letter pattern that most languages have. 

I would propose to use CG for Montenegrin, from "crnogorski". 

This is not an urgent matter, but I believe it's a good idea, and, if not, feel free to explain me why.

Best regards,

Daniel
