Updating 16x16 places:
copied mimetypes/inode-directory to places/folder
That's a duplication but seems somewhere places/folder is used instead of inode-directory and they really have to look the same. Are we allowed to do symlinks?

Updated red/root folder to use the special 16x16 design.
Updated folder-image and folder-html to don't show the folder below. That to improve readability of those.

22x22 might get a similar treatment.
