Don't use an HTML templating tool for CSS

[BevanR]

Handlebars is a great templating tool. It is intended primarily (only?) for HTML templates. However, webfonts-generator uses it for CSS templates. This causes a number of issues;

• Values are HTML-encoded:
  • Complicated values like URLs need to use the triple-brace syntax to prevent HTML encoding of special characters, e.g. {{{sourceUrl}}} to render
  • "ba-icon.eot?0a8c3f7a188a221fd7bc7c97ccd91dc3?#iefix" instead of
  • "ba-icon.eot?0a8c3f7a188a221fd7bc7c97ccd91dc3?#iefix"
  • If using double-braces for simple values, template-rendering takes longer than necessary.
  • If using double-braces for simple values, double and triple braces are used inconsistently.
• IDEs try to format .hbs files as HTML templates, resulting in broken indentation. This is a real pain for projects with standardised auto-formatting IDE policies.

var template = handlebars.compile(source, { noEscape: true }) @ webfonts-generator/src/renderCss.js:71 seems to fix unneeded escaping issues for me but I didn't do extensive testing so not sure if that introduces new bugs
