Previously, this used the e.isMetaDown() check which was failing as
modern Windows keyboards do not have a meta key. Changing this to check
the mouse button fixes right clicking players in a lobby's player list
which now opens a context menu.

When the client encounters a fatal error, it sends a `error-debug`
packet including the last received and sent packages. This can contain
whole maps and easily exceed the current maximum of 250 bytes.

These are sent by clients when they encounter fatal errors and contain
useful information for debugging. Clients also sent an `end` packet
afterwards and that was also unhandled. This is now handled as a no-op.

This logs all outgoing packets.

These are used by admins/sheriffs to do things like mute or ban people.

This currently just joins the multiplayer lobby which is an improvement
over the previous behavior of deadlocking the client and forcing a
restart.

These are handled server-side and assigned initialized as an anonymous
user with names like "anon-xxxx".

Having two classes named `Conn` and `Connection` was a bit confusing.
Now it's more clear that one is the app-agnostic socket-based connection
while the other handles all networking for the golf game.

Also, rename thriftLogs to metadataLogs as that's what they're used for.
