Move the core of this task to a consumable lib?

Reference gruntjs/grunt#522. The grunt-reload task currently relies on a persistent variable set and then having the watch task call it to trigger a reload event. Since the watch task now spawns tasks as child processes this doesn't work anymore.

Should we consider moving the core of this watch task into a lib so other tasks can consume to be notified of watch events? Semi-related to #14. My grunt-hub task would also benefit from this as I duplicate a lot of the functionality there.

Here would be an example on how another task would implement:

var watch = require('grunt-contrib-watch');
watch.on('changed', function(filepath) {
  console.log(this.target); // target that triggered the event
  triggerReload(this.target);
});
// or on all events
watch.on('all', function(event, filepath) {});

Nope. At least not now.
