Removed confusing modification warning from version.js.in

Sure, that is in the output, but it's also in the input!
Corrected all line lengths in doc/

Added mention of liza

The recently liberated work-in-progress framework for which I originally
created ease.js; it's nice to be able to complete that part of this
project's history. :)
