Added a dummy "Notification" plugin, with custom summary and body message.
Not that useful as such, but will be helpful for debugging some rules on the run (by seeing directly in events feed what's happening).

We could add some magic-keys to have replacement of some parts of the string automatically by anything to make it more useful than static text. For example an $IP keywork to be replaced by the IP address (can be used in a rule triggered when changing network)...
Let me know if you have any ideas.

I'm now working on Wifi networks detection (using QNetwork), and cell id localisation (using ofono). I made some tests and it seems to be usable. I'll try to make a trigger plugin for both during the month.

Code will be uploaded to github when possible, and proposed as a pull request.
