First Fixes!

Just fixing some typos and removing some missed stuff (Keys) on the XP page. I'll be making changes as needed for the next couple of days, then look at getting a print version up on drivethru.

... also actually exporting the halfletter with the fixes; you can tell the difference because on the POD format the left side will have a section title, while on the halfletter it doesn't.

Have fun!
