Allows two-line text wrapping for some labels, including:
  - Contest Details: contest name
  - Contest Details: table cell, candidate name
  - Ballot View: Ballot name
  - Candidate Details: candidate name

Also:
  - Adjusts some font sizing down a bit so that more text fits on single lines
  - Smaller candidate image views
