- LAIKAPKT_HANDSHAKE_REQ now only sends the bot's pub key a shared key is generated using the other peer's pub key, allowing for fully encrypted packet bodies, (packet ID is left in plain-text) - laikaS_startOutPacket(), laikaS_endOutPacket(), laikaS_startInPacket() & laikaS_endInPacket() have been added. - laikaS_setSecure() has been added to turn on/off encrypted packets. - genKey now generates kx keypairs - major refactoring for relevant packet handlers - variadic packets have been temporarily disabled
