Massive sanity reorganization of project structure
Overall: - Removed all 'TG' prefixes on classes and enums Service: - TGStationServer => ServerInstance - TGServerService => Service - Moved all ServerInstance partial classes to a subfolder - Moved ChatProvider classes, delegate, and interface to a namespace - 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 - Move PullRequestInfo and DreamDaemonBridge to their own .cs files - Changes the type of ChannelFactory cache from Dictionary<Type, ChannelFactory> to IDictionary<Type, ChannelFactory>
