Home View UI (Unstyled)

TODO (Most likely separate cards):
  - Allow user to select multiple elections on this screen somehow
  - Style the activity/fragment
  - Pass VoterInfo object to VIPTabBarActivity
  - Add VIPError class to handle error responses from the API (always returns null ATM if no valid data)

Current functionality with this PR includes the ability to type an address, and have it return success/failure with an error message, displaying the GO button to the tab view if success.
