Add 'Language' header

[AJenbo]

Poedit needs an additional header to enable spellchecking.

Heres a sample:
"X-Poedit-Language: Danish"

Poedit developer here.

Poedit uses X-Poedit-Language (*and* X-Poedit-Country) to determine the language, true. But it doesn't *need* it if it can determine the language by other means, i.e. by looking at the file name. Poedit 1.4 understands only names that are lang codes ("cs.po", "en_GB.po" etc.), Poedit 1.5 understands anything.LANG.po style too.

Future versions (1.5 or 1.6) will understand the "Language" header (e.g. "Language: en_GB") that will be part of gettext 0.18 and will deprecate these X-Poedit-* headers.

I don't think that we should add support for X-Poedit-Language , since this is a application specific header. I have nothing agains Poedit and it is my favorite editor :)
If we are going on this way we will have to also add X-Virtall or X-Kbabel specific headers.

I guess we can add the "Language" header if it is a standard header in gettext and since it will deprecate the X-Poedit headers.

Since Poedit is very smart and there are many other important things to solve first in Launchpad Translations, this will be a low priority task.

FWIW, I completely agree with you, adding support for this Poedit-specific hack would be waste of time. OTOH, the sooner every producer of PO files supports `Language`, the better.

For reference, here's where `Language` was added to gettext:

Agreed, we should add it. It should be pretty simple too.
