Mod: Conceptual Balance 1.3, updated documentation

[darloth]

I found some spelling errors and other typos, so I fixed them. There were a couple of incorrect mod keywords as well, I'm not sure what they were doing, but now a couple of things in theory will work better.

I've only included the .dm because it's the only file I've changed, you can diff the changes if you want to see what exactly has been done. I've left alone all american / british spelling differences and not changed anything where I wasn't sure of the correct one, but it might be worth checking anyway. If you don't like me correcting your work, that's fine, just tell me and I'll delete the post, but I thought I'd at least offer the chance of other people benefiting from my 10 minutes going through with a spellcheck routine.
