Passive event listener

[RohmatRomadhon]

I have use v0.9.21. Is that added in new version?

Currently, the select component and button ripple effect use touch listeners:

https://github.com/muicss/mui/blob/master/src/js/ripple.js

It sounds like it should be pretty straightforward to use passive event listeners here but it would require testing before putting it into production. Is this something you can work on?
