Demo app needs to be updated
I started integrating Iconics into my application and was using the [demo application](https://play.google.com/store/apps/details?id=com.mikepenz.iconics.sample) to look up icons' name. Some icons that I could find in the demo app were missing from the library and the reason turned out to be #99. It would be great if the demo application can be updated to reflect it
