Documentation: Update acronyms list 

This change adds some new acronyms to the list, clarifies a couple of
points, and fixes a couple formatting issues.

I was planning on leaving this open for a bit and continuing to add
to the patch.  If anyone else wants to help, please feel free to update
this patch as you see fit.
