P-T 1.2

A new update for Party-Timer is out! In this episode:

- The new "Continuous" mode.
You can set an endless sequence of countdowns with a pause between each countdown, a perfect timer for training sessions with a work time and a pause time.

- More options for the sound behavior (on/off was too much minimalist).
Sounds can be now played at the end of the countdown only, in the last 10 seconds only or for each second.

Thanks to Matteo and Ilaria for their suggestions!
