@eonarheim let me know what you think of these changes. I searched for existing test suites for gamepad's isButtonPressed so I could add ones for these new methods, but I only found it referenced in a sandbox, so I updated that instead. If you think there's an appropriate way to test it then I'd be happy to do that!

This doesn't contain the proposed change of renaming isButtonPressed to isButtonHeld as I'm not sure if we're in favour of that or not.

[eonarheim]

@mattjennings That's fine, the sandbox should be okay since there are no unit tests (and I'm not positive how I would unit test the GamePad API either)

I mentioned in the issue, but I'm in favor of the name change for consistency 👍 we can mark the old name @deprecated in the jsdoc and changelog.

@eonarheim perfect, should be good to go now!
