feat(config): add usePolling config

vojtajina · vojtajina · commit 18514d63534c · 2013-10-21T17:12:58.000-07:00
This config option is forwarded to chokidar. When set to `true` (default value is `false`), chokidar uses `fs.watch` instead of stat polling. This seems to be finally working well on linux, however it does not work on Mac. See paulmillr/chokidar#62 That's why I'm leaving it undocumented ;-)
