v0.9.14

**Changes**
- **New**: the `ApiHandler` (and `QuietApiHandler`) constructor takes now a **timeout** in third parameter. The timeout is expressed in **milliseconds** .  The timeout will apply to all API request methods (will raise exception if reached out). Default is **0** (no timeout).
- Formatting
