Item1631: Add (not replace all) icons with custom topic

The %ICON% macro uses a single topic for all of the icons.

If I want to add new icons, I must either:

• modify the DocumentGraphics topic, or
• copy that topic and add my icons to it, and point %ICONTOPIC% at my new topic.

The former is bad because my changes would be lost when I next upgrade.

The latter is better than the former, because I will not lose my changes when I upgrade, but I would not benefit from any improvements to DocumentGraphics when I upgrade, either.

I would like %ICON% to look in an extra topic, if I specify one, so that I can list only my custom icons in a separate topic (e.g. Main.CustomIcons). Foswiki should look for icons in DocumentGraphics and in my topic. My topic should take precedence over DocumentGraphics.

It would be useful if there was also a tool for comparing timestamps of icon image files, to warn the administrator if any images in DocumentGraphics are newer than the corresponding image (if any) in my icons topic.

similarly, it'd be nice if skins could specify different DocumentGraphics topics - which makes me wonder if we shouldn't replace the topic with a tmpl based system, where the distributed & skin settings are in templates/icons.skin.tmpl and then users could specify other customisations using topic templates..

I recon this deserves a feature request

I see FeatureProposals requires a comitted developer. I cannot commit to implementing this kind of change. I don't know enough and I am learning other things right now Would you be willing to implement it?
