A prompt is needed when copying over readonly files

[dwgras]

A prompt is needed asking the user what he wants to do when overwriting a directory or file(s) that have the attribute readonly.

Does the user want to continue or cancel the copy or move operation?

example: Some of the files are marked readonly, do you wish to proceed with the operation?

Presently, the copy/move operation fails with an error message.

Steven had this to say:

This is part of what's needed. The process is a bit more complicated in that, for safety, the check should be done before the copy/move is started. Otherwise, the destination might be partially updated before the user gets a chance to decide what to do.
