Use 'gtx' instead of 't' as client parameter.

Sorry, it seems the same PR as #95.

[kdmsnr]

I think it still needs this patch.

Any clue about the difference with #95 ?

• Using client=gtx (this patch)

http://translate.google.com/translate_a/single?client=gtx&sl=en&tl=ja&q=hello

-> returns json.txt

• Using client=webapp (Prevent odd translation result returned #95)

http://translate.google.com/translate_a/single?client=webapp&sl=en&tl=ja&q=hello

-> returns 403 error

I can't reproduce this problem on my computer. But I checked your referenced links and this issue background. Many users solved by this. And I also tested your "client": "gtx" patch, it works on my machine too. So I think this patch should be merged. @kdmsnr Thanks for your PR!
