Icon library becoming more user friendly

uploading from web possible

I have made a couple of modifications to the icon library. The icons that are not part of any set are now displayed similarly as in the cursor library with 100 icons per page.

Each icon gets its own page, where you can examine all of the images inside the icon.

Logged-in users can now also add icons to the library directly from the web. Adding icons from RealWorld Icon Editor still works, but only for Windows icons. Mac icons cannot be added to the library anymore and they probably never be allowed in again (the Mac icon format is too weird).

Hope you'll enjoy the changes...
