Fix NSLogError and NSLogWarn to use the correct LOG_FLAG constant
so that the level is indicated in the log message.
Remove unnecessary #if 1.
Remove a bunch of #defines that we're not using.
Remove the HTTP log level -- we've never used it.
Remove the VERBOSE log level, and just use DEBUG.

There's no sensible distinction between these two at the moment,
and since the wrapper macro is DLog, the log level should be
named to match.
Fix the Tidbits.framework build.
