Allow optional parameters

Parameters can be made optional by including different versions of URLs with the same name. Such URLs have to have a different number of arguments, e.g.

[
  {
    name: 'optional-param',
    template: 'params/optional/',
  },
  {
    name: 'optional-param',
    template: 'params/optional/${id}/',
  }
]
