[Feature Request]: EX-WebThrottle Gamepad Support

[jcwtm]

Problem/idea statement

I am unsatisfied with current throttle options. I would really like physical controls so touchscreens aren't really my thing. I know HTML5 has a 'gamepad API' and I think that if implemented in EX-WebThrottle, it could provide a cost-effective and easily accessible, simple throttle for everyone.

Of course I could list many drawbacks but simply, a USB controller can be something like $20, which costs much less than and is more easily found in stores than most, if not all, DCC throttles on the market.

Alternatives or workarounds

I currently just click around in JMRI or WebThrottle which isn't very tactile and misclicks can sometimes lead to unwanted results.
