Better packet sending

[UnknownShadow200]

• Need to use NonBlocking sending of data
• Need to rethink how we handle send failures - at the moment, can cause up to 30 seconds of where nothing seems to happen.

The 30 seconds was supposed to be a workaround for a few second dropout, although I don't know how effective that is (or if it even works at all).

It would be amazing if the client can reestablish a dropped connection transparently without the player noticing, possibly with a little help from the server (to sync client side block updates etc that happened while the connection was down)

Eh, client and servers would have to be modified somehow to keep track of last packet other side received and processed (maybe packet ID counter added each packet), and store all unsent packets in the interim. That adds quite a bit of overhead in both network and memory usage.

Not to mention having to consider all the other various details

• Servers have to store per-session state somewhere now
• Server would have to drop unsent packets after certain timeout
• What happens if player was in middle of a minigame
• What happens if map player is on gets unloaded
• etc

Seems a lot of work and overhead for little benefit.
