Remove jQuery dependency

[Reached]

Looks like a cool package :)

Would you be okay with accepting a PR removing the jQuery dependency? I don't think it's necessary, as Sweet Alert don't depend on it?

Keep up the good work!

Thanks for feedback. I am open for PRs but I did not add information about PR or licence to the readme since I am new in open source.
You are absolutely right. The reason why I used JQuery is that, the theme that I use is using JQuery already and this was the easiest way for me.
