Use a configuration object for optional parameters in replace call

[mooeypoo]

The replace method is starting to be extremely verbose in terms of the parameters it allows, and there are several future enhancement considerations that may add even more to it.

The call should be replaced to have the optional parameters as part of a configuration options object, which will also allow for more flexibility in the future.

Instead of

replacer.replace(htmlString, keyFrom, keyTo,baseUrl, bothWays);

It should be something like

replacer.replace(html, this.keys[0], this.keys[1], {
  baseUrl: '...',
  bothWays: '...'
});

And then include other upcoming modes.
