Create bbhelpers.js based on bfb_bootstrap.js

This file is based on bfb_bootstrap.js, but have others nice cards functions: 

toast with a test function for ripple,
app welcome,
invoke contact card,
invoke schedule card,
invoke camera card

All using setup the global card object, so we can call card.<function> from where-ever in the app.

Will be nice implement this new functions and changes on bfb_bootstrap.js file. And make a powerfull helper file.

So good luck. Its easy with coffee.
