New saving system with proper waiting for file flush

Command context for servers now supports Respond()
Chat manager now treats the steam ID Sync.MyId as a local destination, and processes the event accordingly.
Save makes better use of Task<>
Restart actually waits for save
PlayerCollectionExtension uses a dictionary lookup for TryGetBySteamId
Shutting the UI window properly closes Torch
Torch Dispose renamed to Destroy, VRage Dispose marked as obsolete (do not use)
