...via Jasmine::Headless.register_engine hook

In response to issue #102, I added the ability to register custom template engines not currently supported by default in JHW. The hook may be registered by placing ruby code in #{spec_dir}/helpers/spec_helper.rb. (Perhaps the location of this file can be configurable.)

For example, I am using the following to compile Handlebars templates via the handlebars_assets gem for JHW in my current project:

# spec/javascripts/helpers/spec_helper.rb

require 'sprockets'
require 'handlebars_assets'

module Jasmine::Headless
  class HandlebarsTemplate < HandlebarsAssets::TiltHandlebars
    include Jasmine::Headless::FileChecker
    def evaluate(*args)
      if bad_format?(file)
        alert_bad_format(file)
        return ''
      end
      %{<script type="text/javascript">#{super}</script>}
    end
  end
end

Jasmine::Headless.register_engine '.hbs', Jasmine::Headless::HandlebarsTemplate

Nice! Thanks for tackling this, I appreciate it. :) I'm going to mull over the implementation and give it a spin in a few days, then figure out if I want to take it in as-is or suggest changes. Other projects are taking my time right now.

Cool. Perhaps I can help if you're interested in trying another approach.

I've mulled it over and I'm fine with this. Can you also add some info to the docs on the gh-pages branch on how this works?
