Removed all MiniProfile calls that were trying to be simple trace messages (not actually profiling). This doesn't actually

work since MiniProfiler was not meant for that and won't actually output them unless you add Thread.Sleep statements into the using
clauses simply to slow down the application, not ideal. Updated the WebProfiler to log a statement when in medium trust.
