* start work on www page
committing out of paranoia.

thanks @rschamp! This includes:
1. splitting out messages list into a separate component (for clarity)
2. some comment/formatting adjustments for the api calls
3. removal of an extraneous property in emoji-text
* remove duplicate string declaration
* use object.assign instead of defaults deep
we don’t need deep defaults
* fix react warnings
