I didn't think we were using these mediawiki pages any more, but at the last installfest I saw this page on someone's screen, and noticed this error. So I fixed it.
Added verification for heroku installation
Default Heroku stack is now cedar, so less --stack cedaring is required.
Remove the instructions for destroying heroku apps from the command line. It's easier on the web UI, really.
Changed some instructions in get_a_sticker that were referencing '~' to mention the windows option as well.
