Add more ways to specify the base element

[fregante]

3 new ways:

• Handle selectors as the base, like jQuery's $('.base').on('click', '.inner', callback)
• Handle arrays as the base (maybe less useful but comes free with the selector)
• Skip the element, defaults to global delegation: delegate('.inner', 'click', callback)

It'd need tests and docs, but it's a start for discussion.

I like that @bfred-it. Can you add tests and docs?

[fregante]

Done. However I'm not great at mocha tests.

Just started reviewing :)

Sent from GH.

All merged!

[fregante]

Thanks for the prompt review and publish!

[zenorocha]

I published a minor release since it didn't break the API ;)

I noticed the code you wrote on that other pull request. It was written in ES6 and it was much easier to understand. What do you think of replacing Browserify with Webpack and adding Babel to transpile?

Created an issue to record: #22 ;)
