Buttons on Object View may not be recognizable on first glance

• The buttons to Submit observations and Download prediction on the object view could probably be made more clear in the UI.
• Currently the light up when the user hovers over them, but it may be possible that users will actually not recognize them as buttons unless they attempt to click them.
• Other buttons used throughout the app, like the ones used in the signup and login forms could be used instead.
