Add documentation on how to support multiple actions on a single element

[myartsev]

I've spent more time than I'm willing to admit in figuring this out, and now it seems so simple:
<a {{action 'foo' on="click"}} {{action 'bar' on="mouseEnter"}} {{action 'baz' on="mouseLeave"}}>...</a>

Can we add some documentation on how to support multiple actions on a single element?
I think the reason this turned out to be such an unnecessary hassle is the amount of outdated information out there on the web today.

I'm thinking this is the best place for it is before the blurb on attaching actions to non-clickable events?
Happy to write it up and send a PR if you guys think it's useful. I imagine I'm not the first or the last person to run into this!

I think at that point you'd be better off using actions as event handlers, <a onclick={{action 'foo'}} > and such. Can you submit a PR and we'll discuss there?

@myartsev any thoughts here? Would love to get this added into the guides if you have time for that PR ...

My bad, this dropped off my radar.

@locks; can those event handlers be used to handle all types of events? Mouse up, down, etc
If that's the case, why isn't that the suggested way of handling events in the guides?
