--COMPLETED--

### UPDATES:

Good news: youtube videos are showing up
Bad news: background images for the button/image won't show up
Good news: i know why

### CHANGES:

1. Jsoup.clean was blacklisting all of the iframe and embed tags, so i moved those for loops up before the clean
2. Once i did that, i performed the youtube img conversions to show up in the webview
3. Then i did the jsoup.clean line. 

### ISSUES:

whitelist.basicWithImages(): This whitelist allows the same text tags as basic(), and also allows img tags, with appropriate attributes, with src pointing to http or https
This means that you can't get the play button from your assets folder. i linked it directly to github's instance of the image, so you might want to take a look at that too
Similarly, it was stripping out your background image. haven't figured out how to get the whitelisting to not do that.
