#28 Syntax colouring only invokes on keydown

[Maury Markowitz]

If the user types in a query and then presses "Execute", the last word typed in is not check for syntax colouring. For instance, if you type...

select * from city

...and then press Execute, the word "city" does not receive colouring because there was no keydown to trigger the colouring.

The code should trigger on any loss of focus?
