Unity Reboot (Launcher To Quickly Reboot In A Different OS) Updated For Ubuntu 12.10 And 13.04

Today I've updated Unity Reboot to work with the latest GRUB 2.0 available in Ubuntu 12.10 and 13.04.
Unity Reboot is a custom Unity launcher that can be used to quickly reboot into a different OS / Linux distribution, useful for those who dual boot (or triple boot or... it should work with any number of operating systems, including Windows, various Linux distributions like Ubuntu and Fedora, etc.). This isn't just for Unity and it should also work with docks that support Unity quicklists, like DockBarX, Cairo Dock or Plank.
