Adding Google Translate API v2 support

[bmihelac]

Unfortunately Bing translator API that is added in 0.6.3 support only few languages for translation.

Is adding a Google Translate API v2 support reasonable option for you, since it is paying service.

It's definitely a reasonable option and I'll gladly merge it in if anyone provides a working pull request.

Great. I can make the patch, but I am little limited with time currently.

i can make it ,but i don't have any api key for it

if someone can point me in the right direction, (where and how it integrates) I would be glad to do it. I have already integrated the pay version of google translate API in a Django project and have a KEY. The last time i left google api credentials in code the site was so busy it ran up a $200 bill in 2 days :) so if YOU want to test it youll have to provide your own.
