LibLog Breaking change

damianh/LibLog#181 - Sub-components using LibLog ver. 5.0.3 (or newer) will now use MDLC + NDLC (Instead of MDC + NDC) when detecting application is using NLog ver. 4.6. Make sure to update NLog.config to match this change. Make sure that all sub-components have upgraded to LibLog ver. 5.0.3 (or newer) if they make use of OpenNestedContext or OpenMappedContext.
