[latexrefman] Add section on \baselineskip and \baselinestretch

[Hefferon, Jim S.]

I believe I added that section, although I have not gotten the email diff.  

Anyway, just an expansion of what was there.  I think most people thinking about it want to make a double spaced document, so that's what I made the synopsis.  But perhaps others have a different view of the synopsis.
