[PATCH 2/2] Alias cls as clear

[Joe Auricchio]

* commands/minicmd.c: Add clear as alias for cls.

My background is in Unix, so 'clear' comes much more naturally to my
fingers than 'cls'. But it's bad to clutter grub with too many commands.
So I leave this to the maintainers: do we add both commands, only one,  
or
neither?
