displayTimer function now automatically detects what the highest output value type is (e.g. hours / minutes etc) and ensure that it will display the full amount (e.g. 90 mins as hh:mm:ss = 1:30:00 vs 90 mins as mm:ss = 90:00)
changed plugin.js to accurate-js-timer.js and fixed up the demo index.html to demonstrate some of the build in methods of the jstimer object
