When a event has duration zero because the start and end times are identical,
ZeroDivisionError's are raised:
```
Traceback (most recent call last):
File "/home/fortysixandtwo/install/lib/python3.9/site-packages/confy/widgets.py", line 130, in _on_draw
prc = min(max(pos/dur, 0.0), 1.0)
ZeroDivisionError: float division by zero
```
This patch ensures that prc is either 0 if the event is in the future
or 1, if it's in the past.
Closes #18
