Thomas Citharel cc820d6b63
Refactor Core things, including Ecto handling, ActivityPub & Transmogrifier modules 
* Data doesn't need anymore to be converted to ActivityStream format to
be saved (this was taken from Pleroma and not at all a good idea here)
* Everything saved when creating an event is inserted into PostgreSQL in
a single transaction
