Kevin Ballard:
    - Show more detailed timer in Classic mode
    Blocky mode only shows 1 time unit (e.g. "3d" or "2h") due to space
    constraints. We have more space in Classic mode, so go ahead and show 2
    time units (e.g. "3d 7h", or "2h 28m").
    
    Fixes #24.
    - Add Gathering support to the Classic display
