  Log Message:
  -----------
  Updated the way the Client gets the IWidgetFactory.

I updated the Client so that it retrieves the IWidgetFactory using a
static interface method that accesses the Extension Registry. I have
removed several unused components too and made minor adjustments to
other files as required, such as removing files from build.properties. I
fixed a bug in the build that would miss test files that ended in
Test.java instead of Tester.java. I also added an existence test for
IWidgetFactory.getWidgetFactories().
