Implements layoutTestController.overridePreference()

This change provides the infrastructure for
layoutTestController.overridePreference(). Currently, we only provide an
implementation for the preference 'WebKitOfflineWebApplicationCacheEnabled',
which is required by the layout test http/tests/appcache/disabled.html.
