Add bower dependencies for ngRoute

Here's an overview of this PR:
- **Added a bower.json** - needed to install angular-route and we didn't have a bower file yet.)
- **Added .bowerrc** - rename the default _bower_components_ folder to _lib_
- **Modified .gitignore** - added /lib to .gitignore
- **Moved index.html** - moved from within _/client/app_ to just _/client_. /app houses our application js.
