XML/RPC refomatting & file splitting

Hi, I've started to reformate RPC.php - it may be genius code but it's widely undocumented and hard to read. I replaced the tabs with spaces and added basic inline docs the author or someone else who knows the code can complete. Finally I put every class into it's own file. "One class per file" is a good old Java coding rule. PHPDoc needs it like JavaDoc does. I might have broken the code, don't know how to test it. Is there anybody that can help me with it? If not I'd have a strange feeling with the commit... Thanks! Ulf
