browser: support rewriting URLs

I can easily forsee an HTML file that references a file that gets transpiled, so then the extension changes. There should be an option to rewrite those refs during prewrite.

Copied from original issue: makojs/html#8

+1, I needed this for doing static builds, I ended up doing it outside but it'd be better if it was an option inside here, so there's no need to parse twice.

FWIW, this is what I'm using. I guess the configuration part would be the pagedir stuff. But a lot of this could be simplified if it was inside the plugin. Oh also using [email protected], 2.x API doesn't make any sense to me :-|

mako.dependencies('html', function (file, build) {
  if (!file.dependencies().length) return

  const ast = htmldeps.parse(file.contents.toString())
  const deps = htmldeps.extract(ast)
  const pages = params.pages

  deps.forEach(function (dep) {
    if (!dep.path) return
    const abs = path.resolve(file.dirname, dep.path)
    const asset = build.tree.findFile(abs)
    if (!asset) return

    const pagedir = path.relative(pages, asset.dirname)
    const parts = pagedir.split('/')
    const dirname = parts.pop()
    const remaining = parts.join('/')
    const relative = dirname === 'index' ? remaining : pagedir
    const script = path.join('/', relative, asset.basename)

    if (dep.attr && dep.attr.value) {
      dep.attr.value = script
    }
  })

  const html = htmldeps.stringify(ast)
  file.contents = new Buffer(html)
})

Actually re-writing this plugin now, should be much more powerful. Also reducing it's dependency tree a bit :-)
