Next/Back buttons on the analysis screen - "long press" behavior is incorrect.

[anth-git]

On the analysis screen, when I press and hold the Next/Back buttons, the first four moves are executed slowly, and only later they accelerate. I think this is not necessarily what users expect. If I wanted the moves to execute slowly, I would just tap four times, not press and hold. Also, this behavior is different from the older version and from the competitor's app, where a long press makes the moves fast from the start.

I can surely make the acceleration faster, will check that. But:

• making it same as the older version is a non goal
• I do observe a small delay before the rewind is going fast in the competitor app.
