WL-3318

Remove irrelevant bits of tutorial & use English spellings

d/ change to UK spellings, eg, *organise* not organize
e/ as step 5 (or 4 or 6) of the tutorial says "Profile Tool" - I cant see where it is pointing but I don’t think you can access your Profile, you can however access your "Preferences" so change it to Preferences Tool
f/ change "My Workspace" to My Dashboard" throughout the tutorial 
siteName can come from ServerConfigurationService with the ui.service key as we did in the calendar iCal issue.
