Adding transportapi.js to jsdelivr

@jimaek 
Why? 
The name of the bower lib is 'transportapi.js', as it is set in the name.
The github repository is https://github.com/transportapi/transportapi.js - as it is set in the 'repo'.
When you do a bower install transportapi.js - you have this structure bower_components/transportapi.js/dist/scripts
and in there you have transportapi.js and transportapi.min.js, I am excluding the transportapi.js file and I'm leaving only the minified one.

I use similar update.json for my proact.js and it works.
