Updates to the lab environment 1/12/09

* Modified ArcGIS 9.3 install script. Changed variable that for the
location of the 9.2 maps such that it points to their exact directory.
The change was needed because the 9.3 maps use a similar directory
structure.

* Modified Flash 10 Plug-in and Active X install scripts to use a
condition. This will prevent the install from running on a restart.
