2019 preferences

[spencerng]

The preferences/settings activity needs to be updated; most of these changes can be made in preferences.xml.

• FIRST Power Up category should be labeled as Destination: Deep Space
  • See if you can reference the GAME_NAME variable in Constants
  • Alternatively, make a new variable in strings.xml for the game name and reference that throughout the Java code
• Remove the timer increment amount preference
  • We might want to make this hidden instead of deleting it completely, as we might need it for future games
  • We might later decide to scout cycle times this season too, though it wasn't that useful last year
• Remove unused methods (if any) in Settings.java
• Ensure anything that is deleted is done so safely (test the app and see if you can save a data file without crashes)
