Updates for ionic 1.0.0-beta.13 and introducing of bower to install libraries instead of keeping them in the source code

Hi Edwin!

Nice project you have, thanks for sharing it with us! 
I found that your current version of the project working with relatively old version of ionic and after update it fails. Could you please accept my pull request to fix this issue? 
Moreover this patch contains the usage of bower instead of keeping libraries together with source code (what is not the best solution) and I prepared bower configuration files to download necessary libraries.

If you didn't use it before, it is quite simple: you need first to be sure that you have
1) Node.js installed in your machine
2) Install bower: install npm install bower  

And then you can use it by running in the root of project:
bower install

Thanks and regards,
Bogdan
