Add option to disable the Close and Cancel buttons in the Progress dialog

[mfreedberg]

Hello again!
We are using FFS not only for ongoing backups (which is working really well), but also for on-demand system backups as part of XP to Windows 7 migrations. Our configuration settings do not show the progress dialog because the backup portion is embedded in a larger process. Based on customer feedback that the backup phase is confusing (no idea how far along it might be), we are looking for ways to use the progress bar *but safely*.

Would it be possible to add configuration options in the XML that could enable or disable the Cancel button and the Close control for the dialog?

You can check for error code "3" (Helpfile -> Batch Scripting) to detect the user pressing cancel in a .ffs_batch job.
