Set up application to work with ajax, as well as sockets:
added an activities controller
added routes to call appropriate controller methods
added an express setting to disable json pretty printing
added a "sockets" property to the ActivitiyData service object and
changed the behavior of the service depending on what it is set to
removed jQuery and moment services and injections (in preparation for
merge)
refactored ActivityData service
corrected case of a variable
split out routes and socket code into separate files
disabled socket require in app.js
reactivated sockets on the backend as it was causing a 404
Merge branch 'master' of https://github.com/mtdbass5/my-meanstack
