Updated for compatibility with AngularJS 1.2.0 

Updated for compatibility with AngularJS 1.2.0 (now the stable version on angularjs.org) by including angular-route.js and loading it into the application as a dependent module.

Deleted unused modules from app/lib/angular/

Edited to version.txt to reflect current AngularJS version.

Added a new directive which prints the current AngularJS version below the AngularFire-seed version.

Changed AngularFire-seed version number from "0.1" to "0.2" to denote a code change.
