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)
