Adds connection from Nette to Ristretto
Firstly get familiar with Grunt.js and RistrettoExample
// Application startup
Ristretto::register($port = 2013, $container->application);
// or even better
Ristretto::register($filepath = __DIR__ . '/../ristretto.json', $container->application);
# or in config.neon simply as this:
extensions:
ristretto: Ristretto\Extension
# it automatically looks for config file `%appDir%/../ristretto.json`
# and loads Ristretto's port from there
