Share just the dashboard (or be able to edit what we share)#213

Mostly, if I am sharing a public link to a client, its just to show them snippets of info, ie such as the dashboard. It is not to show them everything within sitechecker. It really needs to be editable so we just cna share the dashboard, or anonther part if we wish, rather than having no control over it.

Makes sense, @Darren Lock ! But this is not a quick feature.

Done!
