New Editor - Icon Selector

Hi Guys,

I've already posted an issue about a new feature I completed for h5p-image-hotspots but just thought I'd also share it here as I guess the H5PEditor.IconSelector can be used seperately and in any content-type similar to the color selector. It can be found here: https://github.com/lukemuller/h5p-editor-icon-selector

It's very similar to the color selector in which it's just an input field that takes the fa-**** alias of the icon which can then be applied as a css class to display the font awesome icon. It's based on https://codeb.it/fonticonpicker/ which is great as it allows searching.

Thanks

Luke
