Changed order of actions displayed in projects to priority order
Moved code to display inbox to controller rather than view as it is not actually view logic
Removed $inboxProject from controller as it is no longer being used
Added comment
Amended shouldDisplayAction logic so that it only filters on client_id on screens defined in a filter. All other screens are implicitly filtered or need to be client-agnostic.
Changed all database table names to snake case to avoid issues across OS with capitalisation
