Feature Request: Split / Batch job for larger input

[apple-corps]

I'm trying to translate ~35,000 characters. It looks like there is a limit of characters per engine. However you also provide the live translate option for which we might get banned.

If we have more characters then a single translate job will allow, it would be nice if the program would split and batch the requests. There might even be some time between requests setting so we don't hammer the translation services.

If we have a live translation option, then I think this option is reasonable also.
