LDEV-1989 Stopped author from doing cut/copy/paste (keyboard shortcut) actions on activities when a dialog is open as it was messing with cut/copy/paste of text in the dialogs
LDEV-1947 Editing a competence title now not allowed to change to an existing title or blank, however having trouble making alert appear on on top of the CompetenceDefinitionDialog, so temporary solution is to close the CompetenceDefinitionDialog dialog and have alert appear over CompetenceEditorDialog
LDEV-1977 improving the redirect servlet yet again, now the parameters are all hashed using Base64, so that users cannot recognise patterns in our tool's monitor and learner urls and attempt to access contetn they are not authorised for.
LDEV-1977 make a lams-central action that takes a relative LAMS url and redirects to it, so the users are taken through the login page if neccessary.- Adding checking to make sure that a user cannot access monitor unless they have permission, see LDEV-1978
