Version 2.0-alpha1. Added a new "section" field to the document table.
Unified the default statement types; added PoliticalClaim and
Annotation. Added a "plus" button to statement popup windows to create
duplicates. Added an import function for the old DNA 1.xx XML format.
Replaced instances of HashMap by LinkedHashMap to make sure that the
order of the variables is preserved. Added an "about DNA" window. Added
support for mySQL databases. Added a JDBC driver for MSSQL databases
(without any syntax adjustments yet).
