Rename image on copy

Description

Next (or under) the copy button, add a text field containing the current image name.
If the name is changed, the copied image will have given name.

Detail

Location

I believe that this feature should be best as an optional feature. In other words, it should be accessible from the options menu (on the right of actions) as Toggle Rename.

Usage

When copying we already do cp path/to/source/imagename.img path/to/destination/imagename.img. It should be relatively easy to force the command as cp path/to/source/imagename.img path/to/destination/${textbox.value()}.img where textbox.value() is equal to imagename by default.
