Using Transifex in git.git

Hi Dimitris et al,

[+CC: Git List; for wider exposure]
[+CC: Jonathan Nieder; he has been involved with translations in the past]
[+CC: Junio C Hamano; for authoritative policy advice]

I think it's a good idea to use a system like Transifex to manage
translations for git.git, so that we can attract a large number of
non-technical translators.  Further, I think it's a good time to start
off on this now, since many of the i18n bits from Ævar's series are in
'master'.  So, I'm looking to start off a discussion about how to
adapt a translation system into our current patch workflow.  Dimitris
is the lead developer of Transifex, and can help with the details.

Thanks.
