Notification support

[LinhDNguyen]

Thanks for this software.
Do you have any plan to support the notification? Thank you.

Notification is a must, otherwise its not usable imo. People can't afford to open the app each x minutes to see if there is a message it doesnt make sense no?

Hi @nvl1109 and @jeffgirard

This project and the JamieMagee seem dead so, until they come back alive and I can merge back my changes, you can use and contribute in my branch.

Got notifications support. Nothing to fancy but works.
