October Update: Index, Fudge, Some Additions.

Updated the Compendium to October; a fast turnover, but there were some things that needed early attention:

- The bookmarks (which I didn't expect to be there at all) were worthless; they're now moderately useful, actually naming their pages.  Next round I intend to update them to do the whole "collapse into sections" thing, which will make them *really* useful.

-  "Fudge x3" resolution didn't actually show the dice; I've swapped in plain + and - for now.

- Added a note about how this is largely the result of breaking down traditional games, which influences the structure it's organized into, which could influence things heavily made with it, etc, just as a point of "be aware".

- Tidied up some section intros slightly; nothing critical there.

- Added some new elements towards or at the ends of Guidance, Tracking, and Extras; these are called out with a "New / Updated" tag in the upper right.
