Fix issue with FastClick

The used version of the FastClick library doesn't make the object
available on the global scope, that's why a `FastClick is not defined`
error is thrown in the console.

This commit replaces the fast-click.js with a freshly build version of
the [library](https://github.com/ftlabs/fastclick), build via `make`.
