Lazy loading for Category Icons

[SeNioR-]

I just tested the page in PageSpeed Insights and Google suggested to add lazy loading to category icons.

<img src="{file="$forum->icon" extension="forums_Icons"}" alt='' class='ipsItemStatus ipsItemStatus_custom {{if !\IPS\forums\Topic::containerUnread( $forum ) && !$forum->redirect_on}}ipsItemStatus_read{{endif}}'>

The icons also don't have width and height attributes.

What do you think about it?
