for a better _.template()

the default underscore template tag is <% %>, it's kind of hard to type for me.

so i change this into ``</code>

_ = require 'underscore'

_.templateSettings = 
  interpolate: /``(.+?)``/g

template = _.template 'Hello ``name``!'

prod = template
  name: 'Mustache'

console.log prod

i think this is way much better ;)
