Adding PHPdocs to every class members, in every file. This patch only touches comments, and moved properties on their own lines. Note that some of these properties would need to be moved, somehow changed, or just removed (either because they're old, unused leftovers, or just because we can move them to local scope), but I wanted to keep this patch doc-only.
