Disable the Atmos keyboard's CAPS LOCK for stdio too.

Normally, CAPS LOCK is active because the Oric Atmos's default programming language, BASIC, requires upper-case keywords.  It's turned off if cgetc() is used in a cc65 program.  When I added a console read(), I forgot to turn it off for that input also.  This patch fixes that oversight (better late than never).
So far all source files defining both a constructor and destructor declare and define the constructor first. Please do so here too. The only reason I can see for doing it the other way round as you do is to save a line `.code` which I don't consider a good enough argument for this non-intuitive approach.
