Implement translator for AdventureSettingsPacket (#691)

Browse source 
* Implement translator for AdventureSettingsPacket

The AdventureSettingsPacket is translated into ClientSettingsPacket so the MAY_FLY and FLYING flags are sent to the server. This fixes double-jumping on some servers that rely on the client sending their flying information through this packet.

* Remove top-secret code analysis
