Mail Disable Follower Notification

This module changes the default behaviour of the wizard used to add followers to a record in Odoo (the "Invite" / "Add followers" pop-up available from the chatter of records such as sales orders, projects or tasks).

• The checkbox that controls whether a notification email is sent to the newly added followers is now unchecked by default.
• Users can still choose to send the notification: they simply tick the checkbox before confirming.
• Nothing else changes: the wizard, the list of followers and the way followers are added all work as before.

The change is applied on the mail.wizard.invite wizard, which is the screen Odoo shows when you add followers from the chatter. Because the default is off, adding followers no longer generates notification emails unless the user explicitly asks for them, which helps avoid unwanted emails to customers or colleagues.
