[MiNT] code for Ctrl-6,Ctrl-2

["Helmut Karlowski" <helmut.karlowski@ish.de>]

Hi,

as we are talking about keyboard-input: I just discovered an odd  
behaviour: TOS returns 0x14 on Ctrl-4, 0x15 on Ctrl-5, and 0x1e on Ctrl-6.  
Ctrl-7 is 0x17 in the low byte. So Ctrl-6 is not logically set. The new  
MiNT returns 0x16, as one should expect. In scancode.h (by purec) 0x1e is  
given.

Same for Ctrl-2: 0x02 new, 0x00 old.

Where those codes intentionally given? 0x16 == ^V?
