Details:


This change adds a check at the menu for number keys (0-9), and selects and
continues using the corresponding entry if pressed. 

I made this change so I could operate the grub menu with a hacked up
specialized keyboard that only has a few keys.  I thought it might also be
useful to others making other special purpose systems such as kiosks or
"embedded" systems; or just as a shortcut that saves a keystroke.

 Basically, the menu interface provides a list of @dfn{boot entries} to
