New protocol definition:

<sort - byte>^<from node>^<toaddress (node, user or empty=braodcast)^msgid^hops^data^<simple checksum>
<g1tlh>: all in ascii, no binary allowed, binary character translated to %XX
        and records
<g1tlh>: separtaed with \n
<g1tlh>: links can negotiate zlib compression for link layer
<g1tlh>: This is potentially multicastable which will mean we won't need ax25
        connx
<g1tlh>: anymore
