License not in awkward places

as discussed on ML, the license in the yaml blueprints makes them awkward to use as examples.  similarly (but not yet discussed) having them in *every* html page, since most of these are templates, can result in hundreds of copies of the license in the rendered html.  this causes bloat and slow-down at runtime.  they are not removed by any optimizer (it does not run on html).  the license is in the root `index.html` and so shows up on every page served at runtime; and they are in the JS and CSS (where they do get optimized out).
