Launcher hangs in forever loading on socket error

[SaphireLattice]

In some circumstances, when connecting to a server, launcher will not report that a connection error has occurred, and will falsely report infinite loading despite it being long dead and gone, seemingly freezing on same task for hours

Really need to actually throw an error out into the open

Relevant places: Updater.RunUpdate - ManifestDownloadMissingContent and UpdateBuildManifest

I'm a dumbass the error is manual cancellation.

Though, I do remember that Rkn loves to use RST packets a lot. Weird nothing gets tripped up in the launcher. Hell, at least a timeout of not getting any data...
