It's hard to overstate my satisfaction

Small achievement, but it feels nice none-the-less.  Managed to subclass kiwi.ui.test.common.py's WidgetIntrospecter successfully*, and use it to detect button presses.  I should be able to use the same method to invert the processs -- to simulate button presses.\

Whoops.  Understate != Overstate

*Which means that I was correct about my earlier deductions regarding what the code segments do.  Will post the code shortly.
