Fixed glosbe.com parsing

Hi. 

The glosbe guys have changed their reply format slightly. The language code in the request is a three letter code. In the reply it is a two letter code. E.g. EN instead of ENG.  I have fixed the parsing problem. 

Please, accept this pull request.


I think this would fail in a number of cases:
* If there is a language with code "NG" it will match "ENG", but it is actually a different language.
* What about Swedish? The two-letter language code for it is SV and the three-letter one is SWE.

If you need to do this matching, I think you need to keep a table of ISO 639-1 and ISO 639-2 (or ISO 639-3) language code mappings between the different languages. I think Locale might provide this functionality already.
