Changed the demo page to demonstrate ui.sortable (instead of ui.date).
Updated .gitignore, following the changes from 32287de.
Moved inside 'if (ngModel){}' any code that calls combineCallbacks and added $log.info() message in case ngModel is falsy.
Possibly closes #33 and #34.
Added Instructions about Canceling to README.
Fixing Travis, grunt tests and demo page (because of module updates).
Fixed demo page for angular 1.2
