Hack description

Adds a timer for NES speedruns where the goal is to complete 100 lines. Future additions may include the ability to choose between several categories, as well as a "qualifying" mode for NES Tetris tournaments. Some technical notes:

- The timer assumes a 60fps console, when in actuality most NES's run at ~60.098fps. This is not really a massive issue because it takes over 10 minutes for the error to exceed a second, but the correct time can be found by multiplying the raw time by 60/60.098.
- Pausing is disabled.
- Until the run's completion, the displayed time is actually a frame longer than the actual elapsed time. For some reason the timer stops incrementing the frame before 100 lines is visibly reached, so this discrepancy is compensated for here.
