An option to tweak Update Rollback a bit

[ESSfan 5]

I would like to tweak Update Rollback a bit, i.e an option to choose where Update Rollback files are stored, and confirmation window upon ESET update which asks you to verify where to save Update Rollback files.

Another nice idea

I am unsure how many would take advantage or if demand would be high though.
