Error when DIRS does not exist

[TimVanMourik]

Hi there!
I was using your very useful package, but encountered an error. When the setting TEMPLATES = [ ... ] does not contain DIRS, the following error is thrown:

  File "/usr/local/lib/python3.6/site-packages/livereload/management/commands/livereload.py", line 47, in handle
    watch_dirs.extend(template['DIRS'])
KeyError: 'DIRS

It can be circumvented from my side by making an empty 'DIRS': '' variable in my settings, but it would be nicer if it were fixed in:

django-livereload-server/livereload/management/commands/livereload.py, line 47

Thanks! Keep up the good work :)
