Updated console instructions

Updated console instructions to use the same snippet as the bookmarklet. @jpgohlke, can you update the reddit instructions with these? It will always give the user the latest published version of our code. Tested on Chrome and Firefox. Doesn't work in IE though because github returns the wrong MIME type with the Javascript.

The problem is described here: http://stackoverflow.com/questions/7180099/including-js-from-raw-github-com
and can only be solved by publishing a github page or using rawgithub.com
