Able to upload new icon images straight from gui as well as listing icons found in directory

[TannerW]

Just an enhancement ticket -
it would be really nice if we could upload new image icons straight from the dashboard GUI as well as have a dropdown selection of icons either previously used or detected in the mounted directory. I am happy to put a PR in for this, but I wanted to make sure this project was still alive. If not alive, then I can fork.

This would be very helpful. And of course, an option for a URL to the icon file instead of upload.
