In-browser timer interface

The in-browser implementation is new this year, and is built on the Web Serial API, which itself is new enough that it's not implemented in all browsers.

Some users have reported that their timers aren't being discovered with the in-browser interface. If you're similarly affected, please chime in on bug 169.

If you experience this or any other issues with the in-browser interface, the fallback is to download and run derby-timer.jar to interface with your timer.
