MD WebUI: Update docs for custom iconsets.

MD WebUI: Update docs for custom iconsets.

Simplify instructions and point to the Sites page documentation.

We originally intended to keep the poly-icon.appspot.com URL
in sync with the list of icons, so theoretically we could
visit the URL when iron-icon definitions change in order to
update our copies of them.

However, that's confusing and difficult. And Polymer icons
get updated very infrequently, so it's not worth the hassle.
