[sudo-discuss] Donation guidelines

Hi sudoers. I added some donation guidelines so people will know what to bring and what not to bring to sudo room: https://sudoroom.org/wiki/Donations Now we can just point people here if they ask about dropping off donations. I also added a link to this page from the left menu of the sudo wiki. Of course feel free to edit/append if you don't agree with the list. -- marc/juul
