Fix up Setup Type dialog, and add logic for basic setup

Fix up the Setup Type dialog, by removing an unused function from the page.
Adds logic to the installer to check for a basic or advanced setup choice. Ensures that the service is only installed if the "advanced" method is chosen. Note - it may be possible to remove some defaults from the .onInit, considering they get set through the program now.
