Motivation
Currently before Simplenews sends out the newsletter, a trip to the "Newsletters" tab is required, either before a node is published or after, to queue the newsletter for publishing.
Some users might want this to be automatic and transparent: when a node is published, it is sent out without any further action.
Proposal
Add a checkbox to the admin/config/services/simplenews/settings page, as in the enclosed image.
When this is checked, all nodes are sent automatically when they are published without visiting the "Newsletter" tab.
