[aur-dev] some patches for cleanup and other stuff

In response to a forum thread about stagnating aur development, I worked on the aur a bit when I was bored today. The first patch is probably the most invasive, and I must admit that I haven't tested it (offline -- not dev sandbox). I think the spirit of this patch, if not the implementation of it, is needed. The rss2 -> rss rename would require a simple apache rewrite rule should it go to production. I made notes on the patch itself for my reasoning as to the rename. The rest are misc patches and smaller cleanup elements. Feel free to use some, none, or all of them. -- elij (cactus)
