try 2.1RC, will make release after feedback.

Version V2.1:
 - QPointF support
   * via new Pascal types: TQtPointF,PQtPointF and convenience function QtPointF (like QtPoint)
   * the pascal record TQtPointF is compatible with QPointF internal representation.
   * http://wiki.freepascal.org/Qt4_binding#Solution:Pascalify

 - new QtVersion function (returns qVersion:http://doc.qt.nokia.com/4.5/qtglobal.html#qVersion)
