BIOS (syslinux) and UEFI (grub2) boot: enhance the experience.

- generate the grub fonts (.pf2) ourselves instead of using the
    Slackware-provided grub font file.
- expand the help text about the boot parameters.
- show the liveslak version number in the boot menu.
- remove the 'boot any OS' menu item in Grub because it never worked for me.
- add a bit of Grub help text at the bottom of the screen.

NOTES:
- I do not like the way how I had to implement the Grub2 help menu,
  it is ugly. Perhaps the text artefacts and understrikes are caused by the
  fact that the grub console has to paint on top of the graphical boot menu?
- In any case, the grub console (the black rectangle in the middle) has its
  coordinates hard-coded in the grub2 source so it is not configurable.
- the grub fonts look better than in Beta3 but I am still not happy with them.
