* shared/src -> shared It's not a real package and doesn't even have package.json. This will also make importing less weird if we drop Haste. * Get rid of shared/utils Moved event-specific into shared/event. Moved rest to the root since distinction has always been pretty arbitrary. * Fix references to old shared/src paths
