Add Watchman option to chokidar

[jonricaurte]

Hi,

After looking around different repos, there doesn't seem to be any movement on adding a watchman option to chokidar as was discussed here:

facebook/react-native#628

and here:

ember-cli/ember-cli#4503

Since chokidar supports symlinking, and sane does not (amasad/sane#42), it would be nice to have an option to use watchman and if not fall back to chokidar. Also chokidar seems to perform better than sane.

Thanks.

It's a big job to add a new underlying watch mode. As much as I'd love to see it happen, it's not where my time and attention is at this point.

PR welcome.

Thanks for the quick response.
