Translate whole Language doesn't work: 400 Bad Req

I have been implementing a workaround for this issue.

The problem is that the plugin sends the translation query using the request URL, but if the texts are big, then the maximum of 4K url length is reached and the call fails.
I modified the code to send the data using a POST call instead of a GET call, but google doesn't return the POST data using the same call, instead it creates a one-time address with the result and return it using a redirect. But several versions of unity are not handling redirects fine, and don't even show the LOCATION tag in the response headers, so there is no way to know where to redirect to

So, the solution I'm using now is to fil the original URL until a length of 4K, and that way I can get as many translations as possible in 1 call. But if the source is big enough, google starts failing with the response of "too many queries in a short time", so, I'm now trying to find a balance between how long to wait before calls. I don't want you to have to wait several minutes for all the terms to be processed!

I also added a progress counter, so that it shows how many terms left to be translated!!

Not the best solution, but something around that should work for now. I will send a new beta as soon as I get the final tweaks ready!

Hope that helps,
