Customize HTML templates

[loay]

Customize html templates in strong-error-handler, see strongloop/loopback#1650 (comment) for details.

Configuration options:

// map of templates to use for rendering responses
views: {
  // the default view
  default: path.resolve(__dirname, 'views/error-default.jade'),
  404: path.resolve(__dirname, 'views/error-not-found.jade'),
  // etc.
},

// map of static files to send as a response
files: {
  // default: path.resolve(__dirname, 'public/error.html'),
  401: path.resolve(__dirname, 'views/error-unauthorized.html'),
  // etc.
},

Requires #5

what about something like

"final:after": {
  "strong-error-handler": {
    "params": {
      "debug": true,
      "log": false,
      "htmlRenderer": "$!../path/to/html-renderer",
      "jsonRenderer": "$!../path/to/json-renderer",
      "xmlRenderer": "$!../path/to/xml-renderer",
      "jsonSerializer": "$!../path/to/json-serializer"
    }
  }
}

See my attempt to roll this in: charlie-s@c2335b3

Note that the order of arguments in negotiateContentProducer seemed to be incorrect (#46) so that fix was included in this commit.

Using the above configuration and a function like

module.exports = function sendText(res, data) {
  let content = `${data.name}: ${data.message} (${data.details}) [${data.code}]`;
  res.setHeader('Content-Type', 'plain/text; charset=utf-8');
  res.end(content, 'utf-8');
};

would this help address #6 as well?

is this ever going to be implemented?
