Feature/show contest details

Wait. I'm confused. How does passing an instance of this:
https://github.com/votinginfoproject/android-white-label-app/blob/develop/app/src/main/java/com/votinginfoproject/VotingInformationProject/models/Contest.java
require serialization? 

Don't really care either way, but passing the object to be used directly rather than taking some reference and requiring the Fragment to figure out how to get that object is a bit less flexible, and worse for tests because it couples the fragment to the VoterInfo singleton.
