Needs to have a --delay or --wait flag

[looeee]

A common problem I've found across livereload implementations is that reloading happens once for every file changed.

For example, I'm using Django as a front end to serve static files generated with Hugo.
When I make a change in Hugo, it regenerates around 100 files, and livereload then reloads once for each.

I need to be able to throttle livereloading to prevent this.
