created an error button thing and styled it. now need to make logic to make it show
error handling for ADD. cleaned up a LOT. directive + service.
addIfSleep now will do its own post request to the server. so it does double post requests.  not the most efficient. refactor later
serverside error handling for /post/event
added error for updateEvent in directive, changed put in the service for updateLifeEvent, made sure the timeFrame stays the same. before, it would always revert to month on success of update
/put/event on the serverside with res.send 300 and 200 for errorhandling now
delete function for events in direcive + in service
adding new category = good for both directive and service
category add/delete error handling now on server, directive, service, view
addCategoryTemplate css styling. add and delete are only one two lines now instead of 4. + styled slightly
getUserData in mainCtrl, service, and server
made sure /auth/facebook/callback... with res.cookie, and then res.redirect... is async, with cookie first
