The main menu in the Boot Manager numbers all the menu options.

As you add a new boot device, the hard coded menu option numbers increment.
This makes automated configuration of UEFI more complex.

This patch changes the hard coded menu options to use letters instead of
numbers.  For backwards compatibility, I've left the numbering support in.
However, I've re-ordered the Ebl and Boot Manager entries, so the default
number for the Boot Manager option is now 2, not 3.
