Fix download card getting stuck.

In some scenarios, when a download fails (or hangs), the notification dissapears from the status bar
although it's still in the download manager and after some time it gives a download complete but it really failed.
This change gives the user the chance to cancell the download in this case.

Also, i've fixed the carriage returns (lines added are 89-93)
