Safari issue with haptics - Mouse input no longer works

[terracoda]

I was just using Quad in Safari and mouse input no longer works anywhere.

@jessegreenberg thought this might be related to recent haptics implementation which does work on Safari.

Alt Input with keyboard seems to work fine.

Thanks for reporting @terracoda. We started using tappi in #104 which uses navigator.vibrate to trigger vibrations. navigator.vibrate is not available on safari so when it starts to request vibrations the sim will crash on that platform. We need to do something like prevent its usage on safari or conditionally use tappi in quad or improve tappi to no-op on Safari.

@jbphet do you have a preference for how we continue with tappi work with this issue?

Interesting. I think we should implement some sort of guard to prevent problems on platforms that don't support vibration. In the short term, we could just remove the code if it's causing significant problems for people, and add it back with the guards when we work on this next week.

@terracoda - I've pushed some changes that should prevent this issue on Safari. However, I don't have a good way to test it. Please try it out and let us know if the problem with mouse input is resolved.

I can use mouse input. Seems fixed :-)

Thanks @jbphet!
