Key exchange refactoring!

Browse Source 
- 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
