- Moved EventID and ChatMessageType to their own .cs files
- Moved SanitizeTopicString to Program
- ServerService.cs => Service.cs
- Fixed ProjectInstaller being in it's own namespace instead of
TGServerService
Interface:
- Moved ExitCode enum to Command class
- Moved all components to a namespace
- Moved all component enums to Enumerations.cs
- DDInteropCallHolder => DreamDaemonBridge
