Added fallback icon in case of broken link

[javicebrian]

Hi czeckd!

Please find a attached a proposal for a implementation of a fallback icon in case the icon url is broken. As I found myself the component dispatching a global exception that can't be handled in a local level.

Sorry for the style changes applied by my IDE, using the flag w=1 should make fairly easy to find the real changes, and also it may need some auto-format from your side.

Let me know if you find this useful or you have any suggestion.

thanks!!

J =)

This feature requested in #113, but it never got merged into main and there are conflicts. Do you have cycles to resolve the conflicts? Also, what do you think would be a good way to notify of the error?

Currently experiencing an infinite re-render when the link is broken.
