In 5.0uX we got rid of the "InstallShield" banner in the MSI dialogs. This is done by permanently applying a transform that removes the banner during the build. I believe it's called is.MST and it's in the install ws. Now that we have an offline wrapper, we should do the same thing to the offline installers.
Modified Makefile to apply transform for offline installers.
Created new sponsor tranform to remove the all of the text during the build.
