Confusing button labelling on disk eject dialogue

[Bruno Girin]

When burning a CD ISO to an physical CD using a CD drive that does not support software eject, Brasero displays a message dialogue asking the user to manually eject the CD from the drive (see attached screen shot). Although the message is reasonably clear, there is only one button in this dialogue labelled "Cancel". This is extremely confusing as it suggests that clicking that button will cancel the just finished write operation. Furthermore, the dialogue offers no alternative action that would make sense. A better wording for this button would be "Done". "Close" should be avoided as users may wonder whether this closes the drive or the dialogue.

Steps to reproduce
1. Download an ISO (e.g. Ubuntu server 12.04);
2. Burn the ISO using Brasero and a CD drive that cannot be opened via software;
3. The dialogue appears with its confusing "Cancel" button.
