input.button (submit button)
For waves effect to work properly on submit buttons, wrap the submit button in a i-tag with the classes .waves-effect and .waves-button AND remove the .button class from the input itself.
&.waves-effect only works if function initWaves() was called, see scripts.js
Waves is still under development. I won't do a fully functional implementation before the final release.
Limitations right now:
.circle buttons loses their shadow if .waves-effect is used
submit buttons can't run the animation
the effect doesn't trigger on mobiles and tablets
