Removing lams_support@melcoe.mq.edu.au from the config table as it may be misleading to users, this is the email used by the Forgot Password functionality, and it will retrun undeliverable if someone tries to reply to it.
LDEV-1825: When we copy a learning design, make sure any grouping details and associated mappings attached to a teacher chosen branching or a define later grouped branching are not copied. If we don't do this, we encounter problems when run a design that has been attached to a lesson. Otherwise we either throw an exception (as the grouping doesn't exist) or we use the groupings that were used in the previous lesson and they may not be wanted.
LDEV-1613 Defined two seperate link options in author one for wiki links and the other for external links, instead of just one single option. Fixed up editing option condition for max num edits per wiki page
