Fixed signup bug where user wouldn't be connected to a push notification channel. Fixed the inability to delete other users likes/activities if you're the owner of that String/Photo. This inherently fixed the crashes happening in the liked and activity area. Tagline on login screen. No content views appear when there are no strings/additional content to view in different areas of the app. It also provides the user with an action to discover content. Photo saved properly when creating a single photo string.
