Moved utility functions from pointrel20140202.js to
pointrel20130202Authentication.js
Renamed pointrel20130202Authentication.js to pointrel20130202Utility.js;
updated bootstrap demos
Put SHA256 implementation into pointrel20140202.js to replace using
CryptoJS library version so that the pointrel library could be
stand-alone; removed sha256.js import for CryptoJS from all but one test
file where it is used as an independent test of hashing; fixed unrelated
issue with xContent error message found while looking at JSHint warnings
