Message persistence achieved

TODO:
- Whip Tessy's yellow bottom

Only need Tessy's message encoding now! Once an encoding is set, the
system can accomodate sending multiple messages.
An issue still exists however; HQ somehow reads nothing from a channel,
despite pointing to a correct channel with a valid message. Wondering if
this may have to do with the time at which the message is written?
Someone take a look at this; I have put up a shitload of comments.
