OpenBox Reboot (pipe)Menu.

• setup your grub bootmenu with "default saved" (see info grub for more information)
• make sure you can run the reboot and grub-set-default commands.
• paste this into a file called obreboot.pl and add it as a pipemenu to your menu.xml
• You can now reboot to the boot-option of your choice with a pipe menu!

#
# This pipe menu creates a menu allowing the user to select a grub
# menu item to reboot to. In order for it to work:
#
# 1. The user must be able to run the commands reboot and grub-set-default
# 2. Grub must be configured to with the "default saved" directive.
