Add classy hammer time a version of hammer time which works of class …

…names instead of the style prop

This allows a much smaller payload in SPA's and also reduces the size of hammer-time,
but it also moves away from being a polyfill a little

Questions

• Should we install a 2 line style sheet with native touch action rules when there is native support?
• Should the class options be arrays instead of strings allowing multiple classes per touch-action type?
• Should we abstract the core methods and make MO / Class an extension to core Already decided to do this

Should remove the !MO from here

Looks good other than the one bug, think this will work for class-based hammertime 😄

Regarding the questions:

1. I'd say yes, the expected behavior using hammertime is that these classes will provide that functionality. It should probably be a separate file though, not part of the install method, or overridable via a boolean at least so that users can turn it off if they decide to (which would be weird, but still).
2. I don't think so, convention > configuration. Give users one way to specify the class, it's more performant that way too (though we could convert the array to a map in the install step, meaning it would be about as performant). We can always add that functionality in a minor version bump later on.
3. Yes, the logic is very similar so it makes sense to abstract them out. Ideally we would still be able to only include the one we want to actually use in final builds though, may require an additional build step.

Should we install a 2 line style sheet with native touch action rules when there is native support?

I was going to auto-add something like this for ember-hammertime.

.hammer-time {
  touch-action: manipulation;
  -ms-touch-action: manipulation;
  cursor: pointer;
}

Should the class options be arrays instead of strings allowing multiple classes per touch-action type?

maybe just some presets for the 3 we support?

.ht-manipulation
.ht-none
.ht-auto
