switched to jsdocs from yuidocs

set up uglify to do compression when wanted to produce minified results
build script can tick up semantic versioning
pulled non-breaking PR fixes to Javi's repo
HTML now meets v4.01

Fewer bad width/font error messages

**Currently throwing for SillyClient.js preventing call-home**
Javi, you may want your branch in particular to not have this change.  It's single line and an easy back-patch.

Not Changed:

Still using ES5, should be compatible with existing code
Still using CommonJS rather than modules, should be compatible with existing code
Typescript definitions should still be exactly intact
API should be exactly intact
Objective for this PR is a non-breaking pull. 🤞

Objective:

To let folks downstream take advantage of aforementioned changes.
