No Workbench integration

Some deployments do not require Workbench integration.

These simple cases require a single configuration change in the AppConfig.xml document. This change can be selected during installation, when the user is prompted about whether Oracle Endeca Workbench integration should be enabled.

The following configuration should be changed in the ConfigManager component to disable Workbench integration:
<property name="webStudioEnabled" value="false" />
