- further focus fixes: the new code was a little too conservative in not acquiring focus when a cell is clicked by the user (tested on: examples/example-driven-by-keymaster.html); when focus is lost (=== focus on BODY element) then any cell activation will set the focus to that cell. (Editors would manage their own focus and are assumed to not 'loose focus' like this === not loose focus to the BODY element.)

- AutoTooltips crash fixes.

- AutoTooltips mouse event handlers now use the latest interface spec (i.e. they use what's passed in the extra data parameter with each event; this reduces the amount of userland code to decode basic things as row/column.)
