Typos

Hey Man,

I ran through this as a brain-cleanse before jumping back into code-mode. It was mostly simple punctuation/grammar stuff but there were a handful of instances where I altered word choice or sentence structure because the logic of the statement in question needed some fixing.  Except for the first commit I broke each file into it's own commit so they could be reviewable on an individual basis, should you be so inclined. Happy to do this kind of work more for any other project you've got. It gives me a great excuse to read back through everything and I'm proud to support your work.

Cheers,
Brian
