Renaming following three files and changing html files that refer to
them:
utils_common.js to: pointrel20130202Utils.js
pointrel_utility_classes.js to: pointrel20130202Common.js
pointrel_authentication.js to: pointrel20130202Authentication.js

Note that stored resources for HTML pages that refer to these js files
will no longer be able to find them (not a big issue at the moment).
Removed two unused libraries (sha1.js and sha3.js)
Fixing pointrel-app/index.html to avoid warning
Adding stub index.html at top level
Removing jshint warnings
Adding .jshintrc with devel true to ignore console and alert messages
Adding eclipse external toolbuilder config files
Updating .htaccess file for pointrel-data to deny all access
