Able to edit questionnaires RS text and name
Can disable/enable questionnaires for viewing in admin interface
RS text entered via new CKEditor including ability to insert tokens/template replace text
Added setting table and associated getter/setter functions (currently only used for centre information but could add more)
This means that both the limesurvey and the quexs tables must be in the same database, with the same connection
But has the advantage of being able to join records across tables easily
