Update README.md

Got this trying to run the init command given:

guard init livereload
-bash: guard: command not found

So tried running exec bundle init using:

bundle exec guard init

It worked and installed the necessary Guardfile. Thanks :)

I'm not sure, but probably it should be:

Suggested change

	$ bundle exec guard init
	$ bundle exec guard init livereload

Is not it?

[AlexWayfer]

bundle is not required by Ruby, and it can absent in project with guard-livereload. So… it looks like project-specific case, not general. Like: if you use Bundler — use Bundler.require/setup or bundler exec.

It works for me, thank you.
