Added option to send notification on update.

Looks like my editor changed the spacing of the file. That is why it looks like it has all changed.

• Added config option 'sendNotification': line 48
• Setting notification name: line 75
• Added notify function: line 292
• Calling notify: line 274

Even with ignore whitespace changes one cannot easily say what the real changes are here.
