[latexrefman] Adjustments to easy urls script

[Hefferon, Jim S.]

Just about ready to set this up.  Decided to make the easy url files be softlinks, and to not change the urls inside of the files.

Also added ability to put text into index.html so it can make sense as a top page, where a person who does not know what is up lands.
