Add stylesheet to tasks XML generated by Backup-SchTasks.ps1

[brianary]

The Backup-SchTasks.ps1 script could add a <?xml-stylesheet href="tasks.css"?> or something similar to make that file more immediately readable, when a CSS href is given as a param. Or it could add an XSLT stylesheet for more sophistication.

Alternatively, a separate Export-ScheduledTasks.ps1 could be created that made a nice report.
