Re: ISSUE-164 (char keyCode entries): Add char and keyCode properties to keypress, keydown and keyup entries [DOM3 Events]

This is another straight-forward editorial change. char has been added to keypress/keydown/keyup. Additionally, I added descriptions for char, key, and location. I did not, however, add keyCode as this property is intentionally left out [1].

Thanks,

Jacob
