Add check to make sure .appear is only called once when element stays in view.

[jer2665]

I need something to fire a settimeout when item appears, but 0.3.6 fires that every time you scroll with it in view too. This keeps track of if the element is in view and has appeared, and only triggers appear once, until the element disappears.

I'm working on upgrading my site to jquery3 and the jquerymigrate plugin is complaining on... JQMIGRATE: jQuery.expr[':'] is deprecated; use jQuery.expr.pseudos

This just uses the new way to handle pseudos

Can you be more specific? I just did a test and it's working fine for me. Here are two codepens...

Original jquery.appear.js https://codepen.io/jer2665/pen/QMmbzN/

My changes to script https://codepen.io/jer2665/pen/yoKNGg/

I was using jquery 3, maybe that is the problem. Fork this project and make your version

Codepen is using jquery3 as well, according to $.fn.jquery it's 3.2.1 as of my just checking.
