feat(sort): Add sort option - micah/35/sort

[micahstubbs]

A small PR that adds user-configurable sort for html outputs

Fix #35

a fork of @thaiat's nice PR #41 with a small amount of additional work to get the Travis CI and Appveyor tests to pass.

yea, done. thought it might be related to the linting problem, looks like it's not now. thanks for watching this one 😄

and also, thanks for introducing to me https://github.com/eslint/eslint-plugin-markdown had never noticed this particular eslint plugin before

[micahstubbs]

🎉 hooray, tests are green

Nice! I'm pretty much about to go to sleep for work in the morning and will take a look as soon as I can and get this feature landed 😴

[micahstubbs]

@dougwilson is there anything I can do to improve this PR?

[dougwilson]

I will take a look when I get to a computer.

Are there any plans to merge this PR? Easily sorting by date would be very beneficial.

[micahstubbs]

know that @dougwilson was busy back in August, but maybe, just maybe there's a bit more reviewer bandwidth here in the new year 😄

[mhamann]

@dougwilson i could use this too. any chance on a merge?

[mayeaux]

Ring ring? Sorely missing feature!

[lwouis]

@dougwilson Click the button ;)

[dougwilson]

The sort option should apply to all the response types not just the html one.

[micahstubbs]

looks like the Appveyor node 1.8 env flaked out on us 😢

let's see if I can trigger a second test run 🤔
