Uploading from a URL

I'd like to suggest implementing uploads from a URL, to facilitate the rehosting of dumb memes among other things. Goploader is very neat, thanks!

Hey, thanks!
I've stopped working on goploader for a while now, but that could be a fun challenge. There would be a need to ensure goploader doesn't download the whole file if it's too big, otherwise it would be really easy to fill up disk space using massive files. I don't know if I'll implement that, but if someone makes a pull request regarding that issue I'll be sure to have a look at it and merge it ^^
