For some reason regenerating the images placed them on my machine
with restricted access. This commit stops these files from preventing
things like `ls` `git pull` and other common commands.

Running the automated build using `gulp clean`, `gulp update`, and `gulp compile`
uses attribute 'background-image' instead of 'background' in all '.css' files. Have
css-sprite v0.9.9 installed.

Added a single line to the gulp.js file.  The directory './src/images/emoji'
is deleted when `gulp update` is called, and then populated from the master
branch of emoji-cheat-sheet.com as usual.

I ran `gulp clean`, `gulp update`, and `gulp compile`, removing 4 defunct
emoji images and a css file inside the 'src/images/emoji' folder. This also
removed these items from the 'dist/images/basic' folder, and caused each
of the sprit '.png' and '.css' files to be augmented, since 4 fewer images
were included.

I had some issues with file permissions running these commands.  The were
saved to disk with permissions `rw-r--r--` (644). I had to manually change them
back to their original permissions of `rwxrwxr-x` (755).  Some files were
also 644 by default, including `dist/css/basic/emojify[.min].css` and
`dist/js/emojify[.min].js`.

I did not include the `dist/css/data-uri/` folder, though the '.css' files
were also changed by removing sprites. For some reason, the `background`
attribute was replaced by `background-image`. I'll commit
them next, and can push them up as needed.

Preventing the className calls on SVG elements

…nt will return an `SVGAnimatedString` instead of a string, wich doesnt implements the `match` method.
