Case 14521 clean up.

Cleanup up some diagnostic logging to console that I had added.
Fixed compiler warning, I had missed adding new method recordKeyDown... to header file.


btw, sorry I just noticed that I forked my feature branch from my local master last updated back in early September.
But I thought it was easier to do this cleanup step without pulling down pharo-project/pharo-vm:master merging in between. 
Hopefully that is okay, and I'll pay better attention next time.
