RFE: Display strftime in scheduled backups

If the "strftime substitution" option is enabled in the Module Config for both the "Backup Configuration Files" and "Filesystem Backup" Webmin modules, it would be helpful if the scheduled backups in the list were displayed with the variables substituted instead of just displaying them as entered. This way, it will actually show the name that will be used on the next backup. You could either assume the backup will be run that same day, or get this information from the backup schedule.
