Utils: Create re-usable Callable for copying and asking for overwrite

Browse Source 
FileUtils::copyRecursively has the option to override the copy
operation, and this is e.g. used for asking the user if files already
exist, and to track what is actually copied.

Make that functionality available for re-use.
