use javascript advanced optimizations, improve make-js script

Browse Source 
Major benefit, beside a smaller file size, is the possibility to remove debug informations from the minified javascript.

make-js script:
- take care of any warnings and errors
- raise warning level to verbose

js/*
- switch to Array-Access Property Notation for external data (prevents renaming by the closure compiler)
