Fixed the bug plus:

Rewrote the sync engine to improve performance and resilience.
New retry logic now automatically backs off when rate limits are hit on DigiCert.
Config system now uses json file instead of xml, and all config files are aggregated in the config directory.
Fixed issue with new Keyfactor versions being broken due to lack of DisplayOrder in the metadata fields API.
Fixed issue with email fields not syncing properly.
Implemented a new logging system using NLog, with log files stored in the logs directory, and an nlog.config file.
