[feature-scrub] Updated to verify via css+xpath

Previously, I was searching for Strings.

This was ok for a bit, but its not going to work when I start passing
things through nokogiri to handle emoji via html-pipeline. We're going
to start failing because we're looking for:

<img src="blah/png">

But we actually have the equivalent:

<img src='blah/png'>
Enhanced .features to verify via xpath and css

  [feature-scrub] Updated to verify via css+xpath
[emoji] Added basic emoji feature
[emoji] Finished initial (rough) implementation
[emoji] Added a default CSS file to the presentation

This contains basic instructions for the emoji images.
[emoji] Supported ability to configure an emoji asset_root
[emoji] Created custom emoji-filter

It's presently the equivalent of the EmojiFilter.
[emoji] Updated emoji-filter to remove hard-coded width, height

This might look great on web pages, but it doesn't look that good in
reveal.js slides.

Plus-- users can provide their own CSS-- and removing these inline
attributes gives them better control.
[emoji] Updated emoji-filter to please rubocop.

[no-more-1.9.x] gemspec now asserts support only for >= 2
[emoji] Added spec for CreateSlidesHtml+Emoji
Dropped support for 1.9.x. It's only 2.0.0.

The 'to_h' of OpenStruct introduced in 2.0.0 is now being used to hand
off data between the OpenStruct config and the asset pipeline (which
expects a hash).

* no-more-1.9.x:
  [no-more-1.9.x] gemspec now asserts support only for >= 2
Fixed up README so that badges now display
