Some fixes & improvements

Changes

• Added constants for more readable code.
• The size of the mask (in bytes) for specifying the multi-send target now depends on the number of Connection objects. It used to be 4 bytes in size, now the size is reduced with a small number of players, which saves traffic.

Fixes

• Fixed variable-length UInt32 serialization.

1.1.1

Changes

• Renamed Network Prefab to UNetInstance.

Additions

• Added ByteBufferReader and ByteBufferWriter to help serialize data.
• Added the OnUNetPrepareSend event.
• Added error log if there is not enough connection for a new player.
• Added cleaning of unreliable messages that did not fit in the packet. Switching of this mode is available on the Socket.

Fixes

• Fixed sending queue, now sending starts with reliable messages. This corrected the situation when the size of a reliable message was close to the maximum, which did not allow inserting it into the packet, since the unreliable message was already there.
• Fixed socket initialization, now its initialization directly when connecting locally.
