[Request] Close method and Icon option

[xxRockOnxx]

Would like to have both of those :)
Great work for being minimal!

I'll try to make a minimal change and make a PR for the close method

I think I'll be making a breaking changes. Thought I could just make the closeMessage public and make a growl by doing new growl({ ...opts }). Works for me that way, but the tests failed and hence introduces breaking changes.

I'll just trigger a click to close it.

How would this icon option work? Allow you to define a class or html for the icon? e.g a font-awesome class or even a SVG ?

About the close method, for a simple solution I can think about something like this:
src/index.js line 80
$el.close = closeMessage

Works just fine http://codepen.io/vfreitas-/pen/zZXewx

What do you think? Feel free to make a PR if you want, contributions are welcome 😄

Wow, so glad this is still active.

Yes, either SVG or font-awesome will do. Better if something like:

Option	Type	Default
icon	String/Boolean	false

Now if it's a string, it'll be a class containing the icon you want OR the SVG. That's for the default growl.

If it's growl.error() and the others... add a default icon.

Hmm, I'm not sure tho if it's good to extend DOM element. I'll stick with click for a while.

I've released the version 1.0.0, and now it returns an object containing the element and the close method. So you can just do:

var gr = growl()
gr.close()
gr.$element

About the icon option, I'll try to add it this weekend.

That's what I actually tried but thought it'll be a breaking change so I stepped back. Thanks!
