Log message

Added an exception in the OS X EnsoKeyNotifier so that Enso isn't active while
world of warcraft is active (for some reason, the key re-injection mechanism
doesn't work with WoW).

Also added an NSAutoReleasePool in the event callback so that we don't gather a
massive buffer of memory to release once the key notifier exits.
