fixing bug #964 by making sure the pretty name of the dotlrn static portlets are message keys. In this case the messages have variable lookups for reuse of messages - something I think we want to move away from because it somewhat obscurely requires certain variables to be defined in the scope of the message lookup.
Renamed upgrade script 1.0a3-1.0a4 to 1.1-2.0d1, so it reflects the actual version upgrade, and so it allows us to bump up the version number on 5.0 branch (no data model script there, though)
Check for errors on form before deciding which buttons to display, otherwise it will show the display-mode buttons instead of the edit-mode buttons when there are errors
