Bug 13186: Test for the Navigation Timing API.
Bug 13024: Adding a test for resource timing pref.
Bug 13024: Make sure resource timing is disabled.

This Mozmill test checks if it is possible to get resources with either
of the three available methods (getEntriesByType(), getEntriesByName()
and getEntries()). If so, it fails as this is a clear sign resource
timing has not been disabled properly and may still be active instead.
