Seems that something is up with login on latest firmware. This PR will try to address that (also fix some other bugs)

Fixes issue with simulataenous subscrption of discovery message handler. Now that all discovery happens with a single handller special care needs to be done to handle the case where multiple threads subscribe to all messages
Use new contentless login packet
Don't send -1 ack packets

It seems the new firmware won't accept the 0x02 encryption algorithm and is now using just 0x12. I will have to work out what is going on with it....

Success! The 0x12 encryption algorithm patially encrypts the media packets. Binary data can now be encryted if the encryptionLen is set in the meta data of the packet. Encryption is with the same method as the xml payloads which was, in this case, AES.
