KDE pendrive/external/flash format script.

This script is intended to be placed in device notifier, i.e. when you click on a FS (aka 'drive'), this script should be present with the name format.

You can do this via custom actions in the device notifier settings.

As the title suggests, this's a simple format script made using kdialog which offers formatting options in a verity of FS and also checks the contents of the disk before formatting.

The first argument supplied to the disk should be a partition name (like /dev/sdb1 or /dev/sdd1 etc...).
