I've completely redesigned the uploader. Now it's much more organized into categories, and private and public files are clearly separated.
I've added some categories, but if you think of another one that would be good, just tell me

Also, please add a description for files you upload, and upload them in the right category. I'd like the uploader to be a useful resource by itself, rather than a huge unorganized file heap. Thank you

(And no, there's no way to move/rename the files already uploaded. I'll clean up the mess in the Misc category when I can)
