Enabled the Watchdog Goroutine.
Moved a couple of parser tests into their own file.
Eliminated the hard-coded URLs in TestParser()

Don't run HandleServerSync() on single server setups.
Don't load the user in GetTopicUser(), if the topic creator is the current user.
Fixed a bug in the template generator where endloop nodes were being pushed instead of endif ones.
