EFI3M more friendly for the blind and visually impaired

[Linux for blind general discussion]

Hello,

I just uploaded an new version of EFI3M on GitHub:
https://github.com/DidierSpaier/EFI3M

You can get it typing:
wget https://raw.githubusercontent.com/DidierSpaier/EFI3M/master/EFI3M

This will download the shell script EFI3M that should be run as root.

Enhancements:
I have checked that script can be used with speech using orca.

This is also true on the console using espeakup, only moving a boot
entry up or down while reordering the boot entries is not spoken, I
don't know why.

Reordering the boot entries is now simpler: just select a boot entry
typing its number, then move it with the up or down arrow key. the
corresponding line will be distinguished from the others by a * as first
character.

I will just paste below the second page of the requirements and features
as displayed by the script itself as it details the sound features:

<quoted page below>
Requirements:
GRUB version at least 2.02 should be installed, as well as usual
utilities found in pretty much any Linux distribution.

Sound aid for the visually impaired:
After booting, navigate in the menu with the up and down arrow keys.
If brltty, espeakup or orca is active when EFI3M is run:
1) A Beep is emitted as soon as the menu is displayed.
2) When pressing Enter on the menu entry n (numbered from the top of
   the menu), a tune of n sounds is played. The user can then confirm
   this choice pressing Enter (the same tune is then played again) or go
   back to the top of the menu pressing the Esc key.
3) The same apply to the the last entries, Halt and Reboot. A descending
   arpeggio is played for Halt, a descending followed by an ascending
   arpeggio for Reboot. Again, confirm with Enter or cancel with Esc.

The sound can also be set afterwards: type 4 in the main menu of EFI3M,
then M for Mute or S for Sound, and validate the setting typing V.

To apply the modification to an USB stick you will need to write again
the menu on it, typing 3 in the main menu.
