Preparing for release

Finished porting and verifying all tools from the previous application to the new WPF GUI. Added also more detailed tool tips that explain how the tool should be used.

Made a fix that solves the flickering problems that appears on Windows XP at the OpenCascade OpenGL rendering control hosted on WPF. For this used the tips found here.

Added also tools to the bottom of the window from the status bar. Put there the most used tools for manipulating the view. They can be also found on the View Ribbon Tab.

The current version of application looks like a good candidate for a beta version release.
