Batch processing: more options for "overwrite - ask"

[Peter2]

In Batch processing there are some options for "Overwrite", one of them is "Ask". It is nice for only a few files, but hard for many files. Now there is the standard dialogue "OK / Cancel" - please modify it (like Total Commander) to:
Yes for one / No for one / Yes for all / No for all, cancel batch

I think the problem will be clear of you select 500 files and start converting - but you have forgotten that you already converted them yesterday. Now the user has a problem ...

(Would be fine for XnConvert too ...)
