MP guides to be separate download

A sharp-eyed blogger (Pete Zerger) noticed a change in our management pack download pages. Here's what's going on:

• Guides will be available as a separate download, on the same download page as their respective management packs.
• For a short period of time, guides will still be in the .msi as well. Eventually, the guide will only be available as a separate download and won't be in the .msi package at all. (Why not immediately? It's going to take time for us to communicate this to every team that does a management pack, and we don't want to delay any releases by making a team repackage the .msi just because it still has a guide in it.)

One benefit that we hope to achieve with this is to make it easier and faster for teams to make changes and fixes to the documentation. In our old method, a guide fix meant completely repackaging and retesting the .msi. Now, the .msi won't change so updating the guide will be much less effort.
