More VTK Designer Stuff

The feature additions for VTK Designer is now complete. No more new features will
be added. From now on for another 45 days we are going to fix up the remaining bugs,
package it, give it some shape and put it up for distribution by the end of
next month.

The pic below shows VTK Designer showing a DICOM Image rendered after a
simple Contour Filter. Just one of those days when I was fiddling around
with VTK Designer.

Help system has been overhauled. The complete VTK Designer help along with
all of VTK Class Help is now available within the IDE itself in another
tab stacked behind the code browser.

You can now hover the mouse over any property to see help for the property.

All help tips are extracted from the code comments written by VTK
