Removed trailing white space.

There were several files with trailing whitespace. Removed as some
text editors will automatically make those updates.

Reorganize files for more hackability

The old structure and file naming was based around one canonical layout. The chapter number was included in the filename so that the alphabetical sort order was also the layout order.

Then two things happened:
-We added the Druid smack dab in the middle of the classes
-We got back editor feedback from Jay that certain chapters needed to be reordered

Both of those pointed out how brittle this system was. Adding the Druid file meant renaming all the subsequent XML files AND relinking all the layout files to deal with the changed filenames. That just isn't practical.

This also pointed out that we could make the files more hackable by not baking order into the files themselves. As long as the files have an order built into their names we're tacitly discouraging the hacking of the order of chapters. Once we realized we (DWHQ) wanted to reorder chapters it seemed like a good idea to make it easy for everyone else to.

This change does regress usability of the plain files a bit though. Before an interested reader could read the XML files in the same order as the layout had them just by going in order. We plan to return that capability in another form in a subsequent change.

Have fun hacking the order of the text!
Add InDesign layout files

In the interest of making Dungeon World as open as possible we're now making the InDesign files used for the black & white version of the text freely available under the same license as the text. That means you can remix our layout any way you like.

A few caveats:
-The art is no included. We don't have the rights to make our artists' work CC-licensed. So all art will show up as broken links.
-You'll need two fonts to get the full experience: Newcomen and Archemy. Both fonts require you to pay for a license.

I also can't guarantee that the link to the xml files will work correctly for anyone else. Apparently InDesign stores fully qualified paths (!) to all resources so unless your directory structure exactly matches mine it may not work.

I have tested it a bit and it looks like InDesign will at least try to do a relative path search if the fully qualified path fails. If that holds true all links (except art) should resolve.
