Windows support

Could we get Windows support for node-crontab? Perhaps convert cron entries into Windows Task Scheduler entries, or find a good cron.exe port?

I took a quick glance at Windows Task Scheduler and it may be possible to access through node-ffi. There also seems to be CLI interface although I'm not sure how well supported. Perhaps the biggest problem is that it's been years since the last time I used Windows and I don't have a machine.
