added gradle/grunt integration - helloworld test: gradle grunt_hello
 This is a prerequisite for running angularjs protractor tests via grunt.loadNpmTasks('grunt-protractor-runner');
added grunt/protractor integration i.e. the ability to run protractor tests from using grunt ($grunt protractor).
Haven't yet got gradle/grunt/protractor working.
lmreferenceConf.js -> protractor.conf.js. Plus added comments.
