(bug 47910) Minor edit should not trigger talk page notif

This patch makes Echo talk page notification mimic the existing Orange Bar and Email talk page notification
for minor edit.

For the Orange Bar, minor edit notification is sent if the editor does not have nominornewtalk
permission.

There are additional rules for the email, minor edit notification is sent if global $wgEnotifMinorEdit
is true and notification recipient has enotifminoredits option on.
