TERM=bot mode

[shazow]

This is the beginning of the bot and api modes for ssh-chat.

Primarily, it disables our custom re-rendering pipeline (which emits a slew of control characters that are increasingly hard to parse for bots), it also disables the message echo'ing and defaults to the mono theme. Should be a very clean output that is easy to parse.

This should also make testing easier.

Comparing outputs, default: (using cat -A)

^[[38;05;245m * me joined. (Connected: 1)^[[0m^M^M$
                                                   [^[[38;05;88mme^[[0m] 

TERM=bot:

 * me joined. (Connected: 1)^M^M$
