TextView Indicators When No Event Data Exists

One MVP issue down! Fixes #71.

- Added no data indicators/TextViews if an event doesn't have some data set.
- Fixed bug where events with no short name showed up as blank on the home activity (like the early 90s championships). If an event has no short name, just display the full name like before.
This should line should be something like 
```
if( code == APIResponse.NODATA || adapter.values.isEmpty() )
```
to also show the warning message when we can't load anything from the web
