Small fix for "delete header image"
Invitation mail for new users is sent again
New configuration option:
For forcing wall or box layout when having only a small width available for embed, there has been added a new embed styling configuration, called "Medium Screen Size". It defines the width when changing from desktop-resolution to tablet-resolution. Having this size configured smaller than the available width, the Storyshaker is still shown in wall/box layout instead of one story after another.
