Revert to getScript() for x3dom-full.debug.js (fix missing info-wrapper after clearing cache (..) but breaks minification - use 'gulp' instead of 'gulp prod')

- remove backquotes incompatibles with minification

- remove backquotes incompatible with minification
- load x3dom-full from html instead (to allow minification)
