Gas effects need internal reworking

[Erlend Åmdal]

Gas effects do not sync between client and server, are reset upon restart and are generally clunky to work with with core modding.

Gas effects do not sync between client and server

Do they need to? Forge will reject the client if it doesn't have Gases installed, and if Gases is installed the effects are applied to the player regardless

...are reset upon restart

Are we allowed to store information in player.dat? If so, that will enforce gas effects being sent between client/server. Otherwise, we may be able to store that information locally on the player's computer (/saves/world/glennsgases/data.dat? or simply /config/glennsgases/data.dat, and keep track of SP/MP and world)
