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.

As part of this, make it possible for DRT to configure the timeout threshold between sending touch events to WebCore as the Layout Tests only synthesize single events, not a stream. Because of this, they often get dropped by the WebView for coming too quickly.
Skip the multi touch test as we don't support multi touch in the Browser.
