fix(tvl-ebooks): Update code to bring up to date with reality

Browse source 
Fixes include:

1) users can now opt out of being mkov'd, instead their messages
will be ascii blocked out.

2) highlights are avoided, by learning names from the main tvl
channel and adding a dot after the first char, for example:

> 21:31:35 <•eta-eb> m.ulti: bas1l we quickly connect controller is mostly agreed

3) highlight avoidance is now stored in redis, to avoid restarts
from destroying the map and causing a bunch of highlights
upon restart
