New issue 685: add codeline on install page explicitly telling the user to run the activate script

Cameron Hummels:

some users just scan the install docs for the lines they need to run in order to set up yt, instead of actually reading all of the text.  let's add a single line to this install yt page, which shows in code-mode how to run the activate script, since without running it, yt will break.
