Thanks @arschmitz. Actually I am going to add another commit for #6983 and squash them before merging.

Ready to be reviewed. Commits will be squashed and message from the second commit will be used.

We have a standard contributing guideline that we use for all of our projects. Our larger projects tend to have more information, but there's a push to at least normalize the common stuff. Please take a look at https://github.com/jquery/jquery-color/blob/master/CONTRIBUTING.md which has the standard template and https://github.com/jquery/jquery-ui/blob/master/CONTRIBUTING.md which builds on the standard template.

@scottgonzalez @agcolom - Can you review this PR (again)? Thanks!

[agcolom]

@uGoMobi I'm done. Would be happy for @scottgonzalez to also take a look.

[scottgonzalez]

The consistency issue has been addressed. Thanks.

@agcolom - Can you do the final check and give it the thumbs up when it is good to go? I'll squash the commits before merging. Thanks!
