Small fix.
Update develop.
Merge branch 'develop' of github.com:learningequality/ka-lite into clean_double_messages_fix
Call clear_messages instead of clear_message, since IDs are no longer text-based references.
Make default behavior of doRequest to call handle*API.
No more need for $.ajax; just send parameter tweaks to doRequest.
Allow clearing of specific message types.
Handle all ways APIs currently return messages; reduce # of types by one.
Shift message paradigm to back-end.
