TickMeNot v1.0

Features:

• Displays last 50 unread Whatsapp messages (from notifications), thus preventing read-notification (blue ticks)
• Does nothing else
• Doesn't require internet access or any other special permissions (apart from Notification access)
• For Android Kitkat (4.4) and up

Notes:

• Requires user to authorize access to read all notifications (Settings > Security > Notification access)
• Doesn't support images, rich media, etc.

Known issues:

• May miss a few messages since notifications don't contain full history
• Cycle of duplicate messages
• Contains parsing bugs
• UI needs work (could use an empty view for starters)

Pull requests are welcome! :)
