Shortcut and Start Menu changes to Virtual Sites Advanced Statistics machines

I have enabled the part of the startup script for the Advanced
Statistics Virtual Sites Machines that removes the old shortcuts for
those programs.

To recap: the programs previously had shortcuts in two places, and will
now have shortcuts only in the Advanced Statistics folder. Old shortcuts
were under Course Software on the Virtual Sites machines dedicated to Stats.

The affected programs are:
- HLM 6.0.6
- Sudaan 9.0.3
- Lisrel 8.5
- Mplus 5
- Minitab 15
- Wordsmith 5
- nQuery Advisor 7.0
- Nvivo 8

Users who cannot find these programs in the menu should make sure to
check the Advanced Statistics folder in the Programs menu.

This change will take effect the next time these machines reboot and
process startup scripts.
