. Added URL addressability to dashboards

- the External Access servlet now supports jumping to the My Alfresco dashboard for a user
   - pages other than the default are supported
   - URL is of the form /alfresco/navigate/myalfresco or /alfresco/navigate/myalfresco?page=id

. Added configuration so that the web-client can be configured to jump to any of the following start locations:
   My Home (current defaut), Company Home, Guest Home or My Alfresco dashboard
   see the <initial-location> web-client-config element
